In this JavaScript lesson, we look at "Accessing Nested Arrays in JavaScript, Nested Arrays in Arrays Explained, Learn JS on Codecademy, ". This lesson teaches us how to access values inside of nested arrays using JavaScript. We learn that we are able to chain opening and closing square brackets with index numbers. This allows us to access nested arrays inside of nested arrays! The key to understanding nested arrays is understanding that arrays are 0-indexed. This means that an array list begins counting at index 0. So you target your first array and specify the index your nested array is in. Once you specify your nested array, you can then access an element within that array by chaining the index of the value (or another nested array) you are trying to access. Learning about nested arrays, and how nested arrays work is an important skill for all programmers to have. Being able to visualize data in arrays is important in JavaScript and many other programming languages.
