We're going to start with readable streams. Now, a readable stream reads data from a source and then feeds it into a pipeline bit by bit. For instance, we can create a readable stream that can read from a source array. I'm inside of chapter two, chapter two lesson one, inside of the start folder, and in your index.js file you'll find a sample array of strings. These are local mountain peaks here in the Sierra. So what we're gonna do is we're gonna create a particular type of stream that can read the data from the array and then pass it along chunk by chunk. So, let's see what that would look like.
