JavaScript Compatibility: Is it Supported on All Web Browsers?

JavaScript is one of the most widely used programming languages in the world. It is a popular choice for building web applications, interactive user interfaces, and dynamic websites. However, one of the biggest concerns of developers is whether JavaScript is compatible with all web browsers.

What is JavaScript compatibility?

JavaScript compatibility refers to the ability of a piece of JavaScript code to run on different web browsers without any errors or issues. In other words, it means that the code runs smoothly across all popular web browsers, including Google Chrome, Mozilla Firefox, Safari, and Internet Explorer.
