Check if an array contains a value matching some criterias

JavaScript

const contains = (arr, criteria) => arr.some((v) => criteria(v))

// Or
const contains = (arr, criteria) => arr.some(criteria)

// Or
const contains = (arr, criteria) => arr.filter(criteria).length > 0

TypeScript

const contains = <T,_>(arr: T[], criteria: (a: T) => boolean): boolean => arr.some((v) => criteria(v))

// Or
const contains = <T,_>(arr: T[], criteria: (a: T) => boolean): boolean => arr.some(criteria)

// Or
const contains = <T,_>(arr: T[], criteria: (a: T) => boolean): boolean => arr.filter(criteria).length > 0

Examples

contains([10, 20, 30], (v) => v > 25) // true
contains([10, 20, 30], (v) => v > 100 || v < 15) // true
contains([10, 20, 30], (v) => v > 100) // false
