Angular / TypeScript - Call a function after another one has been completed

Question

I would like to call f2 after f1 has been completed. f1 function can be synchronous or asynchronous.

Answer 1

Just remove the timeout

function f1() {
    return new Promise((resolve, reject) => {
        console.log('i am first');
        resolve();
    });
}

function f2() {
    console.log('i am second');
}

f1().then(f2);
