nameof v0.0.0

nameof

Rather than just the type of an object, get its name. typeof 42 is "number", just like one would expect, but typeof [] and typeof new Date are both just "object". nameof gets the true name of an object.

Examples

var nameof = require('nameof');

nameof(42); // "Number"
nameof([]); // "Array"
nameof({}); // "Object"
nameof(new Date()); // "Date"

function Happy () {
    this.youKnowIt = true;
}
nameof(Happy); // "Function"
nameof(new Happy); // "Happy"

Caveats

Some custom objects, such as those created by anonymous constructors or the Revealing Module Pattern have no specific name.

var Clap = function () {
    this.yourHands = true;
}
nameof(Clap); // "Function"
nameof(new Clap); // ""

function Hokey() {
    function pokey () {
        return 'Turn around!';
    }

    return {
        pokey: pokey
    };
}
nameof(new Hokey); // "Object"

Usage

npm install --save nameof

In a source file, require the module and start using it.

var nameof = require('nameof');
nameof(function Shake() {}); // "Function"
