isInt8Array

isInt8Array :: a → Boolean

Evaluates whether the given value is of type Int8Array

import isInt8Array from 'deep-waters/isInt8Array';

const arr = new Int8Array([21,31]);

isInt8Array(arr); // → true
isInt8Array([21, 31]); // → false

isInt8Array, like any other type validator, is mostly used in composed validators:

import isString from 'deep-waters/isString';
import matchesPattern from 'deep-waters/matchesPattern';

const isEmail = compose(
  isString,
  matchesPattern(/^\w+([.-]?\w+)*@\w+([.-]?\w+)*(\.\w{2,3})+$/),
);

isInt8Array is built on top of ofClass validator and rely on Object.prototype.toString to check on the received value type in order to avoid typeof weird behaviours and encouraging a runtime strict type validation.
