Recursive Promise in javascript

Question

I\'m writing a Javascript Promise that finds the final redirect URL of a link.

What I\'m doing is making a HEAD request in a Promise<

Answer 1

Please check below example for Recursive Promise in javascript/typescript, It will not resolve the promise until number incremented to greater then 13.

below code is suitable for typescript and modify it slightly for javascript.

async iterate(number: number): Promise {
        return new Promise((resolve, reject) => {
            let number = 0;
            if (number > 13) {
                // recursive terminate condition
                resolve(number);
                return;
            } else {
                number = number + 1;
                // recursive call
                this.iterate(number).then(resolve);
            }

        });
    }




this.iterate().then((resolvedData: any) => {
           // wait until number is not greater than 13
           console.log(resolvedData);
    });
