Installation

``
$ npm i --save @cwola/is-typed-array
`

require / import

- esm

import default(== isTypedArray).

`
import isTypedArray from '@cwola/is-typed-array';
`

otherwise.

`
import {

} from '@cwola/is-typed-array';
`

- commonjs

`
const m = require('@cwola/is-typed-array');
const isTypedArray = m.isTypedArray;
const isInt8Array = m.isInt8Array
`
