What Is JavaScript?

JavaScript, or JS, is a programming language that allows the creation of dynamic and interactive websites and applications. It is a client-side scripting language that can be used in conjunction with HTML and cascading style sheets (CSS). JS is often viewed as the foundation of modern web technology, and it has evolved into a powerful tool for creating rich experiences on the web.

JS is a versatile language that can be used to create almost any type of website. However, it is important to understand the nuances of this language before you begin writing your own programs. In this article, we will discuss the origins of JS, its evolution, and the current landscape of this powerful language. We will also explore the most popular libraries for javascript that allow you to add advanced functionality to your web page or application.

What is javascript?

Originally developed for Netscape Navigator in 1995, JavaScript has become one of the most widely-used languages on the Internet. It is a client-side scripting engine that is able to execute code in the browser without connecting to a server and using up valuable CPU resources.

While the syntax of JS is quite similar to other programming languages, there are several important differences that set it apart. Unlike many other languages, which are compiled into machine code before execution, JavaScript uses something called Just-In-Time compilation. This means that the code is compiled into machine code at the time it is executed, resulting in faster performance.

Another unique aspect of JS is its ability to interact with DOM objects in the browser. This allows JS to change the appearance of an entire web page, such as adding new text and images or adjusting the position of an element. It can also be used to manipulate data sent over the network and perform AJAX requests.

In addition, JS is event-driven and can respond to mouse clicks, keyboard inputs, and other events that occur in the browser. It can also interact with various Web APIs that let developers access computing power and services from remote locations.

Lastly, JS is a lightweight language that doesn’t put too much strain on the CPU. This makes it easy to implement, and it is very flexible as well. It is also more compatible with other programming languages than some of its competitors, making it a great choice for web development.
