Generator to Array

Introduction

In this lab, we will explore the concept of generators in JavaScript and how they can be used to simplify the process of iterating over large sets of data. Generators are a powerful tool that allows us to define an iterative algorithm by writing a single function that generates successive values. By the end of this lab, you will have a solid understanding of generators and how they can be used in your JavaScript code.

Converting Generator Output to Array

To convert the output of a generator function to an array, use the spread operator (...). To start practicing coding, open the Terminal/SSH and type node.

Here's an example function that converts a generator to an array:

const generatorToArray = (gen) => [...gen];

You can use this function as follows:

const s = new Set([1, 2, 1, 3, 1, 4]);
generatorToArray(s.entries()); // [[ 1, 1 ], [ 2, 2 ], [ 3, 3 ], [ 4, 4 ]]

Summary

Congratulations! You have completed the Generator to Array lab. You can practice more labs in LabEx to improve your skills.
