What order does JavaScript run code?

What does it mean to say that JavaScript is directly in the head or body of the page? If the code is not enclosed in a function or object, it is directly in the page. In this case, the code runs sequentially as soon as the file containing the code has loaded sufficiently for that code to be accessed.

When does JavaScript start running in the browser?

JavaScript is run in the Client (i.e. the browser). So JavaScript runs after the response from the server has arrived. Let’s add that to our diagram. JavaScript scripts start running as soon as they are loaded, and will continue to run if they have event listeners waiting for events from the user (like clicking, typing, or moving around).

When do you run a function in JavaScript?

In JavaScript, there are times when you need a block of code to just sit back, relax, and not run right when the page loads. This is where JavaScript functions come in. A function is a block of code that runs when we tell it to. In this example, we will show how to run a function when a button is clicked.

Why does JavaScript run after the direct code?

All of this, of course, assumes that your visitor has accessed your page with a browser that has JavaScript enabled. Some users have installed special scripts that may interact with your web page. These scripts run after all of your direct code, but before any code attached to the load event handler.

When does the JavaScript code run sequentially?

In this case, the code runs sequentially as soon as the file containing the code has loaded sufficiently for that code to be accessed. Code that is within a function or object is run only when that function or object is called.
