Try any Node.js package right in your browser

This is a playground to test code. It runs a full Node.js environment and already has all of npm’s 1,000,000+ packages pre-installed, including debounce-promise with all npm packages installed. Try it out:

const debounce = require('debounce-promise') function expensiveOperation (value, delay) { return Promise.resolve(value) } // Simple example { const saveCycles = debounce(expensiveOperation, 100); [1, 2, 3, 4].forEach(num => { return saveCycles('call no #' + num).then(value => { console.log(value) }) }) } // With leading=true { const saveCycles = debounce(expensiveOperation, 100, {leading: true}); [1, 2, 3, 4].forEach(num => { return saveCycles('call no #' + num).then(value => { console.log(value) }) }) } // With accumulate=true { function squareValues (values) { return Promise.all(values.map(val => val * val)) } const square = debounce(squareValues, 100, {accumulate: true}); [1, 2, 3, 4].forEach(num => { return square(num).then(value => { console.log(value) }) }) }
