Learn JavaScript from Scratch JavaScript for Everyone - Timeout and Intervals

The video tutorial covers two JavaScript functions: setTimeout and setInterval. It explains how setTimeout can delay code execution by a specified time using a callback function. The tutorial then introduces setInterval, which repeatedly executes a function at set intervals. It demonstrates how to manage intervals by counting executions and clearing them when a condition is met. The video also discusses practical applications of these functions, such as polling a server for updates, and highlights modern alternatives to avoid unnecessary delays in web applications.
