Returns `true` if the value is a primitive.

Package Exports

  • is-primitive

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (is-primitive) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

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
