How to Reverse an Array in JavaScript

By
I will be writing about how to reverse an array in Javascript on my blog today. 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 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.
