orElse

function Number.orElse<T, U>(
    target: T,
    orElse: (value: Exclude<T, number>) => U,
): Extract<T, number> | U

Returns the numeric value of target if it's a number, otherwise calls the orElse function with the original value and returns its result.

Example

data-first

import { Number } from "@monstermann/number";

Number.orElse(42, () => 0); // 42
Number.orElse(NaN, () => 0); // NaN
Number.orElse(Infinity, (val) => 100); // Infinity
Number.orElse("hello", (val) => val.length); // 5

data-last

import { Number } from "@monstermann/number";

pipe(
    42,
    Number.orElse(() => 0),
); // 42

pipe(
    NaN,
    Number.orElse(() => 0),
); // NaN

pipe(
    Infinity,
    Number.orElse((val) => 100),
); // Infinity

pipe(
    "hello",
    Number.orElse((val) => val.length),
); // 5
