Advantages and Disadvantages of JavaScript

Advantages of JavaScript

  • Speed. Client-side JavaScript is very fast because it can be run immediately within the client-side browser. Unless outside resources are required, JavaScript is unhindered by network calls to a backend server.

  • Simplicity. JavaScript is relatively simple to learn and implement.

  • Popularity. JavaScript is used everywhere on the web.

  • Interoperability. JavaScript plays nicely with other languages and can be used in a huge variety of applications.

  • Server Load. Being client-side reduces the demand on the website server.

  • Gives the ability to create rich interfaces.

Disadvantages of JavaScript

  • Client-Side Security. Because the code executes on the users’ computer, in some cases it can be exploited for malicious purposes. This is one reason some people choose to disable Javascript.

  • Browser Support. JavaScript is sometimes interpreted differently by different browsers. This makes it somewhat difficult to write cross-browser code.
