isEqual

Returns a boolean of whether or not the first parameter is equal in value to the second. Accepts strings, objects or arrays. Optionally pass in a third parameter to enforce loose matching on casing, spaces and order.

TypeScript

export function isEqual<T extends string | any[] | Record<any, any>>(
  a: T,
  b: T
  options: MatchOptions = defaultMatchOptions
): boolean

type MatchOptions = {
  ignoreCase?: boolean // Ignore differences in case
  ignoreSpace?: boolean // Ignore spaces in text
  ignoreOrder?: boolean // Ignore differences in order
}

// Example:

const arr1 = [1, 2, 3, 4]
const arr2 = [4, 3, 2, 1]
 
isEqual(arr1, arr2, { ignoreOrder: true }) //=> true

isEqual(arr1, arr2) //=> false
