Task of Challenge #24

 Create a function that will merge two arrays and return the result as a new array. The two arrays: [9, 8, 7, 6],  [1, 2, 3, 4] .

Solution

Explanation

The function mergeArrays has two inputs (array1 and array2). It also does create an empty array tempArray where the combined and merged array will be stored to.

This time you need two for loops to cover the merging process. You simply push all elements of the first array to the variable tempArray. When this is done, you approach the second array and push also each element into tempArray.

Once you’ve iterated over both arrays and all elements are stored into tempArray you just do the return and already have it. A merged array.

This isn’t the best method you should use. It is a good way to practice loops, but in terms of functionality, clean code, and extensibility you should take my JavaScript Course, where I introduce you also to all kinds of array methods to write maintainable and scalable code – a must-have for every JavaScript Developer.
