Typescript Observer

Simple observer to compliment promise

Usage

Like promise you construct an observer using a callback:

let observer = new Observer<string>((next, error, done) => {
    next("a");
    next("b");
    next("c");
    done();
})

From here you can itterate over the values, a promise is retuened to detect errors/completion:

try {
    await observer.itterate((next : string) => {
        console.log(`Next: ${next}`);
    }) 
} catch(e) {
    console.error(`Error: ${e}`);
}

console.log("Done");
