Is using includes() faster than do-while when iterating trhough an array in Javascript?

When iterating through an array in JavaScript, the fastest method will depend on the specific use case and the size of the array.

In general, if you are looking for a specific element in an array and you want to know if the element exists in the array, the Array.prototype.includes() method will be faster than using a do-while loop.

On the other hand, if you need to perform a specific operation on each element of the array and you need to have the index of the current element, then using a for-loop or forEach will be faster than includes() method.

So, it is recommended to use the appropriate method based on your specific use case and the size of the array.
