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...
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...
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...
Here, we have two CSV strings (csv1andcsv2) that need to be combined into a single array. We split each CSV string and then useconcat()to merge them. Conclusion Adding comma-separated values into an array in JavaScript can be achieved by splitting the CSV string and manipulating the resu...

As an example, the merge sort algorithm is most frequently implemented using recursion. A simple JavaScript implementation of merge sort is as follows: function merge(left, right){ var result = []; while (left.length > 0 && right.length > 0){ if (left[0] < right[0]){ result.push(...
