Understand why Transducers can Improve Performance

Chaining operations like map and filter on an array can have performance issues as we have to iterate through the whole array for every operation.

In this lesson we explore this problem by doing some basic array transformations and measuring their performance.

We’ve got two utility function to help us with this:

• arrayOfRandoms is a higher order function which helps us create a range of random numbers
• timeIt will help us measure how long functions take to execute

It's important to understand this problem and why it occurs before we move on to how transducers handle it differently.
