Because Javascript is a "prototype" oriented language (although, modern
introduction of Class keyword, and the rise of TypeScript has obscured that
somewhat) you can simply do this which was even considered idiomatic a
decade ago:
Array.prototype.reverse = function() {
let start = 0;
let end = this.length - 1;
while (start < end) {
// Swap elements
let temp = this[start];
this[start] = this[end];
this[end] = temp;
// Move to the next pair
start++;
end--;
}
return this;
};
// Example usage:
const arr = [1, 2, 3, 4, 5];
arr.reverse(); // [5, 4, 3, 2, 1]
