A more fine grained typeof that returns e.g. 'array' | 'date' | etc

typeOf.js

/**
 * Description
 * @param {any} value
 * @returns {string}
 */
function typeOf(value) {
    return Object.prototype.toString
        .call(value)
        .replace(/^\[object\s+([a-z]+)\]$/i, '$1')
        .toLowerCase()
}
