Is a given array, string, or object empty? An "empty" object has no enumerable own-properties.
export default function isEmpty(obj) { if (obj == null) return true;
Skip the more expensive toString-based type checks if obj has no
.length.
var length = getLength(obj); if (typeof length == 'number' && ( isArray(obj) || isString(obj) || isArguments(obj) )) return length === 0; return getLength(keys(obj)) === 0; }
