Execute the setInterval function without delay the first time

Question

It\'s there a way to configure the setInterval method of javascript to execute the method immediately and then executes with the timer

Answer 1

There's a convenient npm package called firstInterval (full disclosure, it's mine).

Many of the examples here don't include parameter handling, and changing default behaviors of setInterval in any large project is evil. From the docs:

This pattern

setInterval(callback, 1000, p1, p2);
callback(p1, p2);

is identical to

firstInterval(callback, 1000, p1, p2);

If you're old school in the browser and don't want the dependency, it's an easy cut-and-paste from the code.
