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

For someone needs to bring the outer this inside as if it's an arrow function.

(function f() {
    this.emit("...");
    setTimeout(f.bind(this), 1000);
}).bind(this)();

If the above producing garbage bothers you, you can make a closure instead.

(that => {
    (function f() {
        that.emit("...");
        setTimeout(f, 1000);
    })();
})(this);

Or maybe consider using the @autobind decorator depending on your code.
