isNative

_.isNative(value) # Ⓢ [Ⓣ][1] Ⓝ

Checks if 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.

Since

3.0.0

Arguments

1. value (*): The value to check.

Returns

(boolean): Returns true if value is a native function,

else false.

Example

_.isNative(Array.prototype.push);
// => true

_.isNative(_);
// => false
