    multiply (Functional Programming) es-toolkit

    Creates a function that multiplies its input by a number. Use it with pipe.

    const result = pipe(value, multiply(multiplicand));
    Info

    This helper is specific to es-toolkit/fp. Use it when you want this operation as part of a pipe pipeline.

    Usage

    multiply returns a function that multiplies its input by multiplicand. It is designed for composition: it can transform the value flowing through a pipe, or serve as the callback of a function such as map.

    import { map, multiply, pipe } from 'es-toolkit/fp';

// Transform the piped value.
pipe(3, multiply(2)); // => 6

// Use as a map callback.
pipe([1, 2, 3], map(multiply(3))); // => [3, 6, 9]

    Parameters

    multiplicandnumberrequired

    The number to multiply the input by.

    Returns

    A function that maps value to value * multiplicand.

    (value: number) => number
