JavaScript can be used for Client-side developments as well as Server-side developments. JavaScript contains a standard library of objects, like Array, Date, and Math, and a core set of language elements like operators, control structures, and statements.

  • Light Weight: It is so lightweight, and all the browsers are supported by JS.
  • Handling: Handling events is the main feature of JS, it can easily respond on the website when the user tries to perform any operation.
  • Interpreter Centered: JavaScript is built with interpreter centered that allows the user to get the output without the use of the compiler.

Advantages of JS:

  • In JavaScript, if you ever need any certain feature then you can write it by yourself and use an add-on like Greasemonkey to implement it on the web page.
  • It does not require a compilation process so no compiler is needed user’s browsers do the task.
  • JavaScript is easy to debug, and there are lots of frameworks available that you can use and become master on that.

Disadvantages of JS: 

  • JavaScript codes are visible to the user so user can place some code into the site that compromises the security of data over the website. That will be security issue.
  • All browsers interpret JavaScript that is correct, but they interpret differently to each other.
  • It only supports single inheritance, so in few cases may require the object-oriented language characteristic.
  • A single error in code can totally stop the website’s code rendering on the website.
  • JavaScript stores number as a 64-bit floating-point number but operators operate on 32-bit bitwise operands.
