How to wait until all JavaScript files are loaded before executing JavaScript code?

Estimated read time 1 min read

To wait until all JavaScript files are loaded before executing JavaScript code, you can use the window.onload event. The window.onload event fires when all assets, including images and scripts, have finished loading on the page.

Here’s an example:

window.onload = function() {
  // Your code here
};

In this example, the function passed to the window.onload event will only be executed after all assets have finished loading on the page.

Alternatively, you can also use the addEventListener method:

window.addEventListener("load", function() {
  // Your code here
});

This works similarly to the first example, but uses the addEventListener method instead of the onload property.
