What is an Online JavaScript Runner?

An online JS compiler allows you to write and execute JavaScript directly in your browser without setting up a local Node.js environment. This tool utilizes a sandboxed iframe to securely execute your code and intercepts standard console methods (like console.log and console.error) to display the output visually.
