30. Merge Arrays Without Duplicates Write a JavaScript function that merges two arrays and removes all duplicate elements. Test data : var array1 = [1, 2, 3]; var array2 = [2, 30, 1]; console.log(merge_array(array1, array2)); [3, 2, 30, 1] Click me to see the solution 31...
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...
First, let’s see how you can merge two arrays in PHP using thearray_merge()function. Thearray_merge()function Thearray_merge()function is a built-in PHP function that is used to merge one or more arrays. It takes an arbitrary number of arrays as arguments and returns a new array. T...

Write a JavaScript function that combines two arrays and filters out duplicates using the filter() method. Write a JavaScript function that manually iterates through two arrays to merge them into one with unique values. Write a JavaScript function that handles arrays containing mixed data types when...
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 ...
Moving on to Array.concat(), it is a built-in method in a JS framework. Array merge in JavaScript is possible through concat() or spread syntax for seamless combination. JavaScript merge two objects with Object.assign() or spread syntax to combine their properties. It makes a new array by...
There are two ways to merge arrays. One of them is to use the concat method. The other uses the spread operator ( … ). PS: We can also use the "settings" object to copy anything from the final array. // Merge but don't remove the duplications const merge = (a, b) => a.con...
Bugfix: #merge with {deep: true} no longer attempts (unsuccessfully) to deeply merge arrays as though they were regular objects. 2.0.1 Minor documentation typo fix. 2.0.0 Breaking API change: #merge now takes exactly one or exactly two arguments. The second is optional and allows specifying...
The merge sort algorithm can also be implemented using iteration, such as: //uses the same merge() function from previous example function mergeSort(items){ if (items.length == 1) { return items; } var work = []; for (var i=0, len=items.length; i < len; i++){ work.push([...
