Versions

internal-slot

Truly private storage, akin to the JS spec’s concept of internal slots.

Uses a WeakMap when available; a Map when not; and a regular object in even older engines. Performance and garbage collection behavior will reflect the environment’s capabilities accordingly.

Example

1var SLOT = require('internal-slot');
2var assert = require('assert');
3
4var o = {};
5
6assert.throws(function () { SLOT.assert(o, 'foo'); });
7
8assert.equal(SLOT.has(o, 'foo'), false);
9assert.equal(SLOT.get(o, 'foo'), undefined);
10
11SLOT.set(o, 'foo', 42);
12
13assert.equal(SLOT.has(o, 'foo'), true);
14assert.equal(SLOT.get(o, 'foo'), 42);
15
16assert.doesNotThrow(function () { SLOT.assert(o, 'foo'); });
