Arrays are one of the fundamental and most useful data structures in programming. They are the building blocks of applications and serve as a foundation for more advanced data structures.

Every serious programmer should strive to master Arrays.

The javascript programming language has a strong support for array methods. Let’s look at a few “must know” arrays methods built into javascript.

ForEach

The forEach method is simple yet powerful: you provide a function that will execute once for each array element in ascending order.

An example to illustrate:

	const array1 = ['read', 'clap', 'follow','share'];

	array1.forEach(element => console.log(element));

	// expected output: "read"
	// expected output: "clap"
	// expected output: "follow"
	// expected output: "share"

As displayed above, the forEach method is primarily used when you want to iterate through an array.
