Usage

ESM

import { countArrayTypes } from "array-types-counter";

const counts = countArrayTypes([1, 2, "three", [1, 2, 3]]);
// [{ type: 'number', count: 2 }, { type: 'string', count: 1 }, { type: 'object', count: 1 }]

CommonJS

const { countArrayTypes } = require("array-types-counter");

const counts = countArrayTypes([1, 2, "3", [1, 2, 3]]);
// [{ type: 'number', count: 3 }, { type: 'object', count: 1 }]

API

countArrayTypes(array: unknown[], sampleSize?: number): TypeCount[]

Counts the item types of array and returns them ordered by count, descending. sampleSize limits how many items are inspected from the beginning of the array; it defaults to the array's length and must be a non-negative integer.

• Strings that can be parsed as numbers count as number.
• Arrays and objects both count as object.
• null counts as object (JavaScript typeof).

TypeCount

{
  type: string;
  count: number;
}
