disabled attribute in JavaScript

There are special attributes in HTML that have no values, such as the disabled attribute used to disable elements. In order to set such an attribute, the corresponding property must be assigned the value true, and to remove it, the value false.

Let's see in practice. Let's say we have a disabled input

html<input id="elem" disabled>

Let's output the value of the disabled attribute of this input:

javascriptlet elem = document.querySelector('#elem');
console.log(elem.disabled); // shows true

Now let's enable it:

javascriptlet elem = document.querySelector('#elem');
elem.disabled = false;
