Javascript can add new elements in the page and remove the existing ones. It can also change the CSS of every HTML element on the page. So what can javascript do with the DOM? a lot many things like changing all the HTML elements on the page and all their attributes. It was made dynamic by the introduction of Javascript. During the early time, the web was purely static. The very reason why javascript was created is DOM manipulation. The following are the features of javascript. Developers soon realized that javascript was more than a scripting language. But as the web advanced, features of javascript became more useful. Developers saw many flaws in the language. In the starting, the power of javascript was not known. At that time, javascript was only presented as a scripting language meant only for scripting work, while the java was the original language for heavy and rich web development.īest NodeJS Frameworks Features of Javascript Later that year, the deal between sun and Netscape closed and mocha(also called LiveScript) was renamed to Javascript. Eich started working on it and mocha’s first prototype was introduced in the Netscape communicator in 1995. He had to design a prototype as soon as possible. Other languages like python were also the candidates. Eich had the freedom to do what he likes but there was a lot of pressure on him. This is when Netscape hired Brendan Eich, also known as the father of javascript. A simple scripting language for web and a companion of java.

Netscape wanted to target designers, scripters, and people with no experience of programming. But java at the time was the only popular high-level language and needed well-skilled and experienced developers. The sun technologies were contacted by Netscape to cut a deal to make java available in the browser. So the people at Netscape decided, a simple scripting language can be helpful for making the web dynamic that even the non-developers could use. HTML was also young at that time and it didn’t need big-shot developers. This new scripting language does not need to target big-shot developers. It could all be done by DOM interaction and for DOM interaction, a scripting language was needed. It was realized that the web needed to be more dynamic and the future web should have animations, interactions, and other automation. With more independence and money, they started working on the expansion of the web that gave birth to javascript. They were building their own browser, the Netscape communicator. The same people who worked in the development of NCSA’s Mosaic browser were now working with Netscape communication. The mosaic browser came out as the first popular web browser. Javascript was created by Brendan Eich in 1995 while he was working at Netscape communication.

Javascript has an important part in modern web development. Powerful Javascript libraries like ReactJS are useful while developing not only single page websites, but mobile applications also. Many famous javascript frameworks like AngularJS are used for developing single-page websites. Although, their names sound similar and their syntax is also quite similar, but they greatly differ in design. Syntax of javascript is also very simple and easy to learn. It has flexible APIs for working with a variety of data types like strings, dates, arrays, regular expressions, etc. Javascript greatly helps in DOM manipulation. It supports event-driven, functional, object-oriented, and prototype-based programming styles. Javascript helps in creating interactive web pages. The majority of the web sites in the modern world are developed using javascript and the major web browsers use the javascript engine to execute it. It has a vast amount of features like dynamic programming, prototype-based object-orientation, and first-class functions. It is a client-side as well as a server-side language. Javascript is a high-level programming language that is used widely in the modern web. What is Javascript? What is Javascript used for?
