pipe

Create a new function which pipes its value through the list functions.

const add1 = (n: number) => n + 1;
const times2 = (n: number) => n * 2;

const add1ThenTimes2 = pipe(
    add1,
    times2,
);
const result: number = add1ThenTimes2(1);

assert.strictEqual(result, 4);

Allows first function to have multiple parameters, using generic rest parameters

const difference = (a: number, b: number) => a - b;
const add1 = (n: number) => n + 1;

const differenceThenAdd1 = pipe(
    difference,
    add1,
);
const result: number = differenceThenAdd1(5, 4);

assert.strictEqual(result, 2);

pipeWith

Transform a value by piping it through the listed functions. Sugar syntax for pipe(f, g)(value).

const add1 = (n: number) => n + 1;
const times2 = (n: number) => n * 2;

const result: number = pipeWith(1, add1, times2);

assert.strictEqual(result, 4);
