This skill helps you choose and apply the right es-toolkit utilities in JavaScript or TypeScript codebases.
Use this skill when the user:
es-toolkit/compat during migrationWhen the user asks for helper utilities or refactors:
array, function, math, object, predicate, promise, string).es-toolkit or scoped paths like es-toolkit/array to keep bundle size small.es-toolkit/compat if behavior parity is required before deeper refactor.pnpm add es-toolkit
// import from '@es-toolkit/es-toolkit' in jsr.
import { chunk, debounce } from 'es-toolkit';
const debouncedLog = debounce(message => {
console.log(message);
}, 300);
// This call will be debounced
debouncedLog('Hello, world!');
const array = [1, 2, 3, 4, 5, 6];
const chunkedArray = chunk(array, 2);
console.log(chunkedArray);
// Output: [[1, 2], [3, 4], [5, 6]]
