A community-maintained cheatsheet documenting modern JavaScript concepts frequently encountered in contemporary codebases, focusing on ES2015+ features like arrow functions, destructuring, and array methods. It is aimed at developers with basic JavaScript knowledge who need to get up to speed with modern syntax and patterns.
Use cases
- learn modern javascript syntax for es6 features
- understand arrow functions and this binding
- quick reference for destructuring objects and arrays
- brush up on map filter reduce array methods
- get familiar with modern codebases before learning react
- review var let const differences
When to choose
- you already know basic JavaScript and need a refresher on ES6+ syntax
- you want a concise reference rather than a full tutorial
- you are transitioning from older JavaScript to modern codebases
When to avoid
- you are a complete beginner learning JavaScript from scratch
- you need exhaustive language documentation or spec-level detail
