About stdlib...

We believe in a future in which the web is a preferred environment for numerical computation. To help realize this future, we've built stdlib. stdlib is a standard library, with an emphasis on numerical and scientific computation, written in JavaScript (and C) for execution in browsers and in Node.js.

The library is fully decomposable, being architected in such a way that you can swap out and mix and match APIs and functionality to cater to your exact preferences and use cases.

When you use stdlib, you can be absolutely certain that you are using the most thorough, rigorous, well-written, studied, documented, tested, measured, and high-quality code out there.

To join us in bringing numerical computing to the web, get started by checking us out on GitHub, and please consider financially supporting stdlib. We greatly appreciate your continued support!

Native Class

Determine the specification defined classification of an object.

Installation

1npm install @stdlib/utils-native-class

Usage

1var nativeClass = require( '@stdlib/utils-native-class' );

nativeClass( value )

Returns a string value indicating a specification defined classification of an object.

1var str = nativeClass( 'a' );
2// returns '[object String]'
3
4str = nativeClass( 5 );
5// returns '[object Number]'
6
7function Beep() {
8    return this;
9}
10str = nativeClass( new Beep() );
11// returns '[object Object]'

Notes

The function is not robust for ES2015+ environments. In ES2015+, Symbol.toStringTag allows overriding the default description of an object.
```
1var toStr = Object.prototype.toString;
2
3var str = toStr.call( false );
4// returns '[object Boolean]'
5
6var o = {};
7str = toStr.call( o );
8// returns '[object Object]'
9
10// Mask the default description:
11o[ Symbol.toStringTag ] = 'Boolean';
12
13str = toStr.call( o );
14// returns '[object Boolean]'
```
While measures are taken to uncover the default description, such measures can be thwarted. While this function remains useful for type-checking, be aware that value impersonation is possible. Prefer functions tailored to checking for particular value types, as specialized functions are better equipped to address Symbol.toStringTag.
