Arrays are used to store a collection of multiple items under a single variable name. This collection could be things like strings, numbers, or even a mix of different data types. Sometimes we need to update or manipulate our arrays by adding or removing items, or combining one array with another. In this guide, I’ll go over just some of the many basic JavaScript array methods. Methods we’ll discuss include: .push(), .pop(), .shift(), .unshift(), .indexOf(), .toString(), .join(), & .concat().
