JavaScript Code Typing

Built for working JavaScript developers who want to stop fighting their keyboard and start flowing through real code. You will type real snippets covering arrow functions, destructuring, spread, optional chaining, async/await, and array methods like map, filter, and reduce. The payoff is muscle memory for the symbols and patterns you write every single day.
