Loop over all methods in an object?

Say:

var foo = {
    bar: x => x * 2,
    baz: x => x / 2,
    bam: x => x + 2,
};

and then something like (I'm not very acquainted with loops in JS): 

for (let method; method in foo.keys()){
    // for every method in `foo`
    console.log(foo[method](5));
};

I just started learning JavaScript, and the syntax is probably wrong. But you get the idea...

Sure. You could do something like this:

var foo = {
    bar: x => x * 2,
    baz: x => x / 2,
    bam: x => x + 2,
};


Object.keys(foo).forEach(method => console.log(foo[method](5)))
