isFunction

A TypeScript type guard that checks whether a value is callable, narrowing it to a function type so you can safely invoke it in your code.

Usage

Check whether a value is a function. This is a TypeScript type guard function.

import { isFunction } from '@movk/core'

isFunction(() => {}) // => true
isFunction(Math.abs) // => true
isFunction({}) // => false

isFunction(value: any): value is (...args: any[]) => any

value

any required

boolean

Returns true if the value is a function, otherwise false.

isNumber

A TypeScript type guard that checks whether a value is a finite number, excluding NaN, so numeric logic stays safe and predictable.
