12 August 2020

To start the construction of your website you need a language to do programming and JavaScript is one such programming language that will help you to implement complex things to your web pages. From the simplest web page to the most complex and animated work of art, everything works out with the involvement of JavaScript with other two important parts HTML & CSS.

JavaScript lets the user to dynamically update content, controlling multimedia and almost everything. JavaScript was developed in NETSCAPE which now stand alone among other programming languages. It was originally developed to have a user interaction with the web pages components and to assign the browser with asynchronous communication to control the browser.

Under mentioned Followings are a few of the many uses of JavaScript. Keep reading …

1. Helps with Browser Security

There exist thousands of browsers and each one of those has their own running codes which are called “execution environment” in technical term. Each code runs and works independently without having any influence on codes running along in other tabs or browsers. From this point of view, it can be seen that JavaScript is a great tool for browser’s security as pirates would not be able to copy and steal the data. If such a functioning of JavaScript becomes nonfunctioning then the pirates would easily copy and steal the information from other websites, which is a bad thing.

2. Provides Dynamic Functionality

JavaScript is not only limited to client-side scripting but also has the capability to work with server-side scripting and creating real-world applications. An HTML page would be termed as static without the presence of JavaScript and it would become dynamic with the use of JavaScript. Displaying Flash content is only possible if you make use of JavaScript while programming your web pages and web content. Its dynamic quality goes to the extent that it not only works with web content but also with various external applications like PDF documents, running widget and to enable the page with special effects like a roll in, rolls out etc.

3. Manages Web Pages Content

For any changes or addition to the content displaying on your webpage JavaScript comes in handy. Same thing appearing on your web page will make it dull and boring for your viewers, thus always changing web page seems a necessity for you. For example, creating a button that always changes the color when you click it will change the general outlook of your dull web page. It helps you by validating your form information filled by authenticating the details, it makes your information unique and easily accessible among hundreds of similar portfolios.

4. Easy to learn

Unlike many other languages that stand out for programming purposes, JavaScript is quite easy to learn as a beginner who has no experience or knowledge of such things. With its compatibility to write complex codes in short and understandable format, it becomes the first programming language that you should learn. With the simultaneous testing in the browser, it will enable you have a look at the changes and to observe how it worked out. With its unique way of functioning as an interpreted language within a browser, it will make you easily understand and write the language.


Just remember that your website or web page will not be available if JavaScript is not available. Things that you are going to create with it must fulfill users’ goal of reaching a task much faster and with ease. Your site must not break, if such things happen you are not using it right. To say, JavaScript is the backbone and part and parcel of the working of web content, by letting you edit and diversify the content with adding graphics and flash content to your website. JavaScript is very much similar to other programming languages, so understanding it will help you understand others fast and easily.
