  • Since all modern browsers support JavaScript, it is seen almost everywhere. All the famous companies use JavaScript as a tool including Google, Amazon, PayPal, etc.


  • Since the JavaScript code is viewable to the user, others may use it for malicious purposes.
  • The older browsers don’t support some new functions and we need to check them as well.
  • If the error occurs in JavaScript, it can stop rendering the whole website. Browsers are extremely tolerant of JavaScript errors.
  • Though some HTML editors support debugging, it’s not as efficient as other editors like C/C++ editors. Hence difficult for the developer to debug the errors.
