How to select an HTML element by its ID using JavaScript?

To select an HTML element by its ID using JavaScript, you can use the getElementById() function.

Here is an example:

// Select the element with the ID "myElement"
var element = document.getElementById("myElement");

// Manipulate the element using JavaScript
element.style.backgroundColor = "red";
element.innerHTML = "New content";

In this example, the function getElementById() is called with a string parameter representing the ID of the element you want to select. This returns a reference to the element, which you can then manipulate or work with using JavaScript.
