Disadvantages of JavaScript

In this article we will learn about Disadvantages of JavaScript.

There are two main disadvantages of JavaScript. 

Security : JavaScript runs on the client machine. So a malicious user may use JavaScript to do a variety of things like tracking your browsing history, stealing passwords etc. This is one of the main reasons why people disable JavaScript.

Browser Compatibility : Not all browsers treat the same piece of JavaScript in the same manner. This means the functionality and the user interface may vary from browser to browser. That is why cross-browser testing is very important. However, with JavaScript libraries like jQuery Browser Compatibility is no longer a major issue.
