we will learn how to get the unique elements in the resulted merge array or remove duplicate elements from the resulted merge array. In this topic, we will explain the three different ways to merge arrays and get the resultant merge array in JavaScript. ...
Theconcat()method is used to join two or more arrays. This method does not change the existing arrays, but returns a new array, containing the values of the joined arrays. 代码语言:javascript 代码运行次数:0 运行 AI代码解释 console.log(a.concat(b)); 当字符串处理 代码语言:javascript 代码运...

Array 1: Include Help Array 2: Learn Programming Merged array: Include Help Learn Programming Merging two mutable arrays (arrayBuffers)We can assign the concatenated array to any of the existing arrays when they are mutable. Both methods, concat() and ++ apply to ArrayBuffer also. A method ...
const sortedArray = mergeSort(array); console.log(sortedArray); // Output: [1, 2, 3, 4, 5, 6, 7, 8] This code defines two functions: mergeSort and merge. The mergeSort function recursively splits the array into halves until it reaches arrays of length 1. The merge function then ...

To combine the two arrays without any duplicates, first we need to combine the arrays using the es6 spread(…) operator then pass it to the new Set() constructor to remove the duplicates. Note: The spread(…) operator unpacks the iterables (such as sets, arrays, objects, etc) into a...
