| Video Discription | How to split array into chunks in javascript? How to split array into chunks or sub-array using JavaScript? How to divide array data into parts? How to make chunk array in JavaScript? This can be a good JavaScript interview question or leetcode problem to solve. One way of splitting array into chunks is such that we define a function called chunkArray that takes two arguments, "myArray" and "chunkSize". A const will store results array. Initially index will be 0. Use a while loop to iterate over the elements in "myArray" in chunks of size "chunkSize". The loop starts at index 0, and at each iteration, it pushes a new sub-array of "myArray" to the "results" array, starting at the current index and ending at the current index + "chunkSize". The index is then incremented by "chunkSize" so that the next iteration will start at the next set of elements. The function will return the "results" array, containing the chunks of the original array. At the end, in console log, we passed the array with array size and it is returning array of chunks or array of sub-arrays. Another way is to defines a function called chunkArray that takes in two arguments: an array called myArray, and a number called chunkSize. Define results variable with empty array. Use a while loop to break the input array into smaller arrays, or "chunks", of the specified size. The loop continues to run as long as the input array is not empty. Each iteration of the loop, the code uses the slice method to create a new sub-array from the input array, starting from index 0 and ending at the specified chunkSize. This sub-array is then added to the results array using the push method. Finally, the input array is updated to remove the just-chunked elements by using the slice method again, this time starting at the chunkSize index and ending at the end of the array. Return results. Define an array called myArray and pass it to chunkArry function to break it up into chunks of size 3. The resulting chunks are logged to the console. Another way is to define a function called "chunkArray" that takes two parameters: "myArray" and "size". Define an empty array called "results", which will be used to store the chunks of array. Use a for-of loop to iterate through each element in the "myArray" parameter. Inside the loop, create a variable called "last" which is equal to the last element in the "results" array. Check if the "last" variable is undefined or if the length of "last" is equal to the "size" parameter. If either of these conditions are true, push a new array containing the current element of the loop to the "results" array. If these conditions are false, the current element is pushed to the last array in "results". After the for-of loop finishes executing, return the "results" array which now contains chunks of the original array of size specified by the "size" parameter. Call the function with an array containing elements of your choice and size as the arguments, so it will return results that is chunks of original array. Given array has been divided into two chunks. Alternatively define a function called "chunkArray" that takes two parameters: "myArray" and "chunkSize". Return an array created by the Array from method. It will have two arguments, the first one is an object with a single key-value pair: that creates an array with the length of the ceiling division of the length of the input array by the chunkSize. The second argument is a function that will be called for each element of the new array, it receives two arguments, the current element and the index. Use the slice method of the input array, to select a portion of the original array and return it as a new array. The slice method takes two arguments, the start and end of the slice, i in loop is the current index of the array. Call the function with an array of your choice and size as the arguments. The returning value is chunks of array. This code is a more concise version of the previous code snippets, it uses the built-in array methods to achieve the same result in fewer lines of code. So this is how you can split array into any number of chunks in JavaScript. * Full Playlist (Coding Challenge, Interview Questions & Leetcode) * https://youtube.com/playlist?list=PL1w28LzkbaQHF_HmdZUD0h3lz2p4PzO0A It can be a good javascript interview question or frontend interview question.
