const compose = (...fns) =>
fns.reduceRight((prevFn, nextFn) =>
(...args) => nextFn(prevFn(...args)),
value => value
);
Create the function, composed of three others:
const example = compose(
val => { console.log(1); return `1<${val}>`; },
val => { console.log(2); return `2<${val}>`; },
val => { console.log(3); return `3<${val}>`; }
);
Call the function:
example('hello')
Console output is:
3
2
1
"1<2<3<hello>>>"
Hello!
@kevinwucodes the idea there was so that
prevFn
is always a function.@nem035 I like that, thanks. I wasn't aware
reduceRight
was available.
