How Does Learning JavaScript & jQuery Compare to Other Languages?

Recognizing how unique JavaScript and jQuery are is essential when comparing them to other programming languages. One of the main differences between JavaScript and other languages is that it is a scripting language and does not have to be compiled to be implemented. 

It is said that JavaScript and Java are both simple to learn, but JavaScript may be slightly easier for beginning programmers as they don’t need any tooling to get started. JavaScript is a scripting language, while Java is a network-centric programming language. JavaScript and Java surprisingly have little in common, as JavaScript is used for web and browser-based application development, while Java is used for app development. 

When compared to Python, JavaScript responds to mouse clicks and keystrokes, while Python responds to function calls. JavaScript Developers may use Python on the front end. Learning Python may cost between $3,000 and $5,000, and learning JavaScript may cost between $1,000 and $5,000. It is more expensive to learn JavaScript as part of an undergraduate program than to take comprehensive bootcamps and certificate programs. When comparing JavaScript to C, Javascript is compiled with the just-in-time compiler, while C is compiled in advance. JavaScript is not a markup language, which makes it more challenging to learn than HTML. 

For those wanting to learn jQuery, the more JavaScript they know, the better off they will be. jQuery is a feature-rich JavaScript library, but it cannot replace JavaScript. It is optimized for scripting functions with fewer lines of code and is considered easy to learn. Many experts consider it to be easier than learning JavaScript.

How to Decide the Best Way to Learn JavaScript & jQuery
