We will cover several of these methods in this series, each in their own post. Some iteration methods, like () iterates over all items in a collection and some like () iterates over the array partially. slice(), some() and every() are such examples. There are other iteration methods which are not as often used, but when needed are always handy tools for iterating over arrays, strings and objects. Common examples of iteration methods in JavaScript are (), () and (). Iteration is the process of looping through a collection of data and acting on each item in order to manipulate the item or create a side effect from it. Creating Arrays from a List of Arguments.These operations, especially with arrays and strings, are very common in front end development with libraries like React and Angular. In this series, we cover several methods that are used to iterate over a collection of data, act on them or produce side effects. Here’s a sample function that splits an array into multiple smaller arrays:įor (let i = 0 i < arr.This is a series on sparsely used iteration methods in JavaScript. In the function, loop through the original array, and within each iteration, use the `slice()` method to create smaller arrays of the desired size and push them into a new array. Create a function that accepts an array and a chunk size as input arguments.ģ. Determine the desired size of each smaller array, which would be called ‘chunk size.’Ģ. You can split an array into multiple arrays in JavaScript using the `slice()` method. We will also provide usage examples so that you can see how it works in practice.
In this blog post, we’ll look at how to use the `slice()` method and a simple function to split an array into multiple smaller arrays of desired size. The `slice()` method is the perfect tool for this job, as it allows you to create new sub-arrays from existing ones. Splitting an array into multiple smaller arrays can be a useful task in JavaScript.
