    Primitive values

    The Mozilla docs for "Primitive values" defines specifies six data types that are primitives:

    • Boolean
    • Null
    • Undefined
    • Number
    • String
    • Symbol (new in ECMAScript 6)

    Usage

    var isPrimitive = require('is-primitive');

    true

    All of the following return true:

    console.log(isPrimitive(false));
    console.log(isPrimitive(true));
    console.log(isPrimitive(null));
    console.log(isPrimitive());
    console.log(isPrimitive(42));
    console.log(isPrimitive('abc'));
    console.log(isPrimitive(Symbol()));
    //=> true

    false

    Everything else returns false:

    console.log(isPrimitive({}));
    console.log(isPrimitive([]));
    console.log(isPrimitive(function(){}));
    console.log(isPrimitive(new Date()));
    // et cetera...
    //=> false
