Apply Transform Over Each Element in Array

Given an integer array arr and a mapping function fn, return a new array with a transformation applied to each element.

The returned array should be created such that returnedArray[i] = fn(arr[i], i).

Please solve it without the built-in Array.map method.
In this video, we'll explore the concept of array transformation and learn how to create our own map function in JavaScript. We'll solve the problem of applying a transformation over each element in an array without using the built-in Array.map method.
Here's what we'll cover:
🔹 Understanding the purpose and use cases of array transformation.
🔹 Step-by-step guide to creating a custom myMap function.
🔹 Implementing the transformation logic using a loop and a mapping function.
🔹 Live coding demonstrations and practical examples to reinforce the concepts.
🔹 Comparing the custom myMap function with the built-in Array.map method.
🔹 Best practices and performance considerations when working with arrays and transformations.
By the end of this video, you'll have a solid understanding of how to implement your own map function and apply transformations to array elements. This knowledge will deepen your understanding of array manipulation and functional programming in JavaScript.
Get ready to unlock the power of custom array transformations and take your JavaScript skills to new heights!
