We can use the combination of fetch and eval() to execute a JS file in another JS file.Never use the eval function as it possesses security risks and it is far too easy for a bad actor to run arbitrary code when you use eval().įor example, if you use the eval on the server-side and a user used an infinite loop as their username, then it may crash the computer leading to server downtime. The eval function evaluates JavaScript code represented as a string.Įvaluating the JavaScript code means it runs the code which was passed to the function in a string. Then we are accessing the code of the JavaScript file using the text function and stored it in utilsText then passed it to the eval function. We are waiting for our HTML page to load and then fetching the utils file using fetch. Let's rewrite the earlier greet example using require in Node JS.Ĭreate a new file utils.js with the following code: Node JS has the module system even before the introduction of ES6 modules in JavaScript.

We need the type="module" attribute in the element to declare this script as a module.
