value is a pristine native function.
Note: This method can’t reliably detect native functions in the presence of the core-js package because core-js circumvents this kind of detection. Despite multiple requests, the core-js maintainer has made it clear: any attempt to fix the detection will be obstructed. As a result, we’re left with little choice but to throw an error. Unfortunately, this also affects packages, like babel-polyfill, which rely on core-js.
value(*): The value to check.
value is a native function, else
_.isNative(Array.prototype.push); // => true _.isNative(_); // => false
