How to Reverse an Array in JavaScript

In order to achieve reversing an array in JS without the reverse method, you can use a combination of a for loop or an array push method. 

Let's take a look at this example: 

Write a function, reverseArray(), that takes in an array as an argument and returns a new array with the elements in the reverse order.

function reverseArray(arr) {

const output = new Array;

for(let i = arr.length-1; i >= 0; i--) {

output.push(arr[i]);

}

return output;

}

//uncomment the code below to test in your IDE:

//const sentence = ['sense.','make', 'all', 'will', 'This'];

//console.log(reverseArray(sentence))

//Expected output: 

'This', 'will', 'all', 'make', 'sense.' ]

This example is one of the most popular entry level interview questions for Javascript. I hope to solve more questions like this and also use this piece as a reference when needed. That will be all from me today. Until next time, remember to stay positive.
