What Is a Front-End Developer?
- The front-end developer is one who is comfortable with the Front-end Technology, Front end Framework, and working with the API’s.
- To design the front end part of the application, we are mostly using front-end technology such as HTML, CSS, and Javascript.
- The latest version of HTML is HTML 5 and CSS has CSS4 which is enriched with lots of new functionality like Improved support for embedding graphics, audio, and video content via the new <canvas>, <audio>, and <video>
- It has the Extensions to the JavaScript API such as geolocation and drag-and-drop as well for storage and caching.
- Several new semantic tags were also added to HTML 5 which complement the structural logic of modern web applications. These include the <main>, <nav>, <article>, <section>, <header>, <footer>, and <aside> tags. New form controls, such as <calendar>, <date>, <time>, <email>, <url>, and <search>.
- The CSS is another major component for Front end development where for styling language which is simple enough for HTML elements. It is popular in web designing, and its application is common in XHTML also.
- It has the many variations such as CSS1, CSS2, CSS 2.1, CSS 3, and CSS 4.
- It has good Bandwidth, Site-wide consistency, Page reformatting options and Good Accessibility with Content separated from presentation.
- It is a having pre-planned libraries, which allows easier and more standards-compliant webpage styling, using CSS language.
- Related to Framework, We can use JavaScript to make the page more dynamic by adding the event-based responsive pages.
- The more common examples of scripts which are mostly used by the front-end developers are Angular.js, React JS, Node JS, Database & Cache, etc.
- Related to API’s, The API are the Application Programming Interface which is used to get developed in HTTP & REST.
- The HTTP is used to establishes the communication between the server and the client.
- The Rest is a lightweight replacement for RPC for the designing of networked applications.
HTML, CSS, & JavaScript:
As we have already discussed above the HTML, CSS, and JavaScript are considered as the Front end technology which is used as a basic tool for developing the web page. The major important facts are discussed as below.
HTML:
- The HTML is the HyperText Mark-up Language and considered a major tool for front-end development.
- The HTML 5 is the latest tool for front-end development which consists of rich content that is used to deliver the graphics and it doesn’t need any additional plugin.
- Provide better semantic support for web page structure through the introduction of new structural element tags.
- It is used to Provide better cross-platform support with the help of its advance tags such as <main>, <nav>, <article>, <section>, <header>, <footer>, and <aside> tags and new form controls, such as <calendar>, <date>, <time>, <email>, <url>, and <search>.
CSS:
- It is another major component that is basically used for styling the document. It has many variations such as CSS1, CSS2, CSS 2.1, CSS 3, and CSS 4.
- It has good Bandwidth, Site-wide consistency, Page reformatting options and Good Accessibility with Content separated from presentation.
- It is having pre-planned libraries, which allows easier and more standards-compliant webpage styling, using CSS language.
- The CSS can be integrated in any web document in three ways:
- Inline: Style attribute can be used to have CSS applied HTML elements.
- Embedded: The Head element can have a Style element within which the code can be placed.
- Linked/ Imported: CSS can be placed in an external file and linked via a link element.
- Another major feature of CSS is Embedded Style Sheets using which we can able to perform the following in web pages, such as:
- Multiple tag types can be created in a single document.
- Styles, in complex situations, can be applied by using Selector and Grouping methods.
- The extra download is unnecessary.
- With its Selector Function, it can able to get compact and able to access any valued attribute.
- The design and customization of documents are rendered by media. By applying media control over the external style sheets, they can be retrieved and used by loading it from the network.
Java Script:
Like HTML and CSS the Java Script is also another tool through which we can make our web page more dynamic and effective.
- Using Java Script we can enable the light threaded programming concept in the Static HTML web page.
- It has its different datatype concept, which help us to enable the programming concept in web pages. The data types are Undefined, Null, Boolean, String, Symbol, Number, and
- JavaScript is an OOP scripting language whose code is run on a browser only.
- It is specially designed for creating network-centric applications.
- It is complementary to and integrated with Java.
- It is an open and cross-platform scripting language.
Besides the above, the major utilization of Java Script also includes the following.
- It requires Less server interaction – Here You can validate user input before sending the page off to the server. This saves server traffic, which means less load on your server.
- It has the Immediate feedback to the visitors – Here we don’t have to wait for a page reload to see if they have forgotten to enter something.
- It enriches the Increased interactivity − You can create interfaces that react when the user hovers over them with a mouse or activates them via the keyboard.
- It has more collection of Rich interfaces – Here it includes such items as drag-and-drop components and sliders to give a Rich Interface to your site visitors.

Front End Frameworks
Experience with RESTful Services and APIs:
It is the most advanced and important front-end designing framework tool which is used for developing the front end of the application. Its important feature is as discussed below.
- It is stateless so we need to refer to it every time as long as we need to use it.
- It will be necessary to remind it of our data.
- It is used to support the JSON and XML features so it can be made easily compatible with it.
- It is simple than SOAP. So, it is widely used as a replacement of SOAP in most the application design.
- Here the documentation is very easy and comfortable.
- It is more friendly, if any error is get found it can easily inform the user with appropriate punctuation.
Responsive and Mobile Design:
The responsive approach of front-end has many important facts that is why it is very popularly being used in now a day. The important feature is discussed below.

Git and Version Control Systems
- The Git which is also referred as (/ɡɪt/) is a distributed version control system for tracking changes in source code during software development.
- It is mainly designed for coordinating work among programmers so that the chances of error at the integration phase will be get reduced.
- It can also be used to track changes in any set of files if required by the developer at the time of developing the application.
- Similarly, the Version control systems are a category of software tools that help a software team manage changes to source code over time.
- The Version control software keeps track of every modification to the code in a special kind of database.
- If a mistake is made by the developers at the time of developing the application then they can turn back the clock and compare earlier versions of the code to help fix the mistake while minimizing disruption to all team members.
Problem Solving Skills:
It is the most important ability for any development firm when we are going to have the product to be get developed. During the Application development, the following are the listed points which must be required as a major parameter for the problem-solving skill.
- It must have an Active listening prospect.
- The Analysis is very much an essential factor here.

Web Browsers (most common) and Headless Browsers:
The major differences between the Web browser and Headless Browser are listed below.
| Headless Browsers | Web Browsers |
| It is the form of a web browser without a graphical user interface(GUI). | It is the form of a web browser with a graphical user interface(GUI). |
| It usually provides an API to manipulate the web page/DOM, download, and to manage the resources. | Here the interaction with a website is done with a mouse and keyboard using a browser with a GUI present on the head section. |
| It doesn’t have the actual render content. | It does have the actual render content. |
| Here the functions like loading a page, run scripts like normal, access the DOM like normal same as a web browser. | Here the functions like loading a page, run scripts, access the DOM are present with render content of the document. |
| HTML parsing, cookies, XHR, some JavaScript, etc are supported up to an average extent. | HTML parsing, cookies, XHR, some JavaScript, etc are fully supported. |
Web views:
Whenever we need to accessing internet content, we mostly use a browser like Chrome, Firefox, Safari, Internet Explorer, and Edge. Here the Web Views is another option that is used to provide us the same functionality but in a better manner.
- A WebView is an embeddable browser that a native application can use to display web content.
- A native app is defined as the app which is written in the language and UI framework designed specifically for a particular platform.
- As we know that a browser usually has two parts, such as the UI (address bar, navigation buttons, etc.), and the other part is the engine.
- Here the engine of the browser is used to turns the Markup and code into the pixels we can see and interact with.
- With the Web View, this flexibility opens up a whole world of code reuse between your browser-focused web app and the parts of your web app that you want to display inside a native app.
- Here the JavaScript is well running inside your WebView has the ability to call native system APIs.
- The most important fact is here that, By default, any web code running inside a WebView or web browser is kept isolated from the rest of the app.
- For better functioning of host and security reasons that revolve around minimizing the extent of damage, some malicious JavaScript might be able to do.
Native from Web Tech:
- A native app that is also referred to as a native application is a software application built in a specific programming language, for the specific device platform, either iOS or Android.
- Unlike web apps that are written primarily in Javascript, the native apps are applications that are mostly written in languages that the platform they are being built for accepts.
- The most common example includes, Swift or Objective-C is used to write native iOS apps, Java is used to write native Android apps, and C# for the most part for Windows Phone apps.
- It is usually a Fast and Responsive, most reliable, and most responsive experience to users.
- It is easy to tap into wider device functionality so we can easily tap into the camera, microphone, compass, accelerometer, and swipe gestures super easy.
- It can have the ability to Match app UI/UX to platform conventions to the platform conventions.
- Here There exist dozens of UI/UX differences that make users feel at home. By building native, you don’t have to compromise with UI/UX that you hope will be user-friendly for all platforms.
