JavaScript Promises
Explore JavaScript promises to manage asynchronous code effectively. Understand how to create and handle promises, use Promise.all to wait for multiple promises, and apply Promise.race to process the fastest result. This lesson equips you with key skills to handle async operations in JavaScript for smoother code execution.
Synchronous JavaScript operations
Like the name implies, synchronous operations execute in sequence. Each line of code or function is executed one after another.
const sum = 34 + 67;
const multiply = 56 * 56;
The code snippet above executes the first statement and then, if no error occurs, the second statement executes.
Synchronous operations block the execution of more statements to ensure that currently-running statements complete execution before another begins.
Asynchronous JavaScript operations
An asynchronous JavaScript operation is one that’s non-blocking. The code doesn’t ...
