.push()

The .push() method adds one or more elements to the end of an array and returns the new length.

array.push(item1, item2, ...itemN);

A comma-separated list of items (strings, variables, or functions) can be passed to the end of the array. The .push() method is not to be confused with returning an entirely new array with the passed object.

Add one item to the end of the colors array:

const colors = ['red', 'orange'];
colors.push('yellow');

console.log(colors);

This will output the following:

["red", "orange", "yellow"]

The following example adds multiple colors to the colors array:
