setImm

setImm is a JavaScript function that schedules a callback function to be executed after a specified delay. It is part of the Web Workers API, but it can also be used in the main thread. The function returns a unique identifier that can be used to cancel the scheduled execution using the clearImm function.

The syntax for setImm is:

const id = setImm(callback, delay, ...args);

callback: The function to be executed after the delay.

delay: The delay in milliseconds before the callback is executed.

args: Optional arguments to be passed to the callback function.

Example:

function greet(name) {

console.log(`Hello, ${name}!`);

}

const timeoutId = setImm(greet, 2000, "World"); // Logs "Hello, World!" after 2 seconds

To cancel the timeout, you can use:

clearImm(timeoutId);

setImm is similar to setTimeout, but it has some key differences. setImm is designed to be more efficient in scenarios where multiple timeouts are scheduled, as it can batch them together. It also guarantees that the callback will be executed as soon as possible after the delay, even if the main thread is busy. This makes it particularly useful for scheduling non-critical tasks that should not block the main thread. While it's part of the Web Workers API, its availability in the main thread makes it a versatile tool for managing asynchronous operations.
