WeakSet.prototype.clear()

Obsolete
This feature is obsolete. Although it may still work in some browsers, its use is discouraged since it could be removed at any time. Try to avoid using it.

The clear() method removes all elements from a WeakSet object.

Syntax

ws.clear();

Examples

Using the clear method

var ws = new WeakSet();

ws.add(window);
ws.has(window);  // true

ws.clear();

ws.has(window); // false

Specifications

Not part of any current specification or draft. This method was part of the ECMAScript 6 draft specification until revision 28 (version of October 14, 2014), but has been removed in later versions of the draft. It will not be part of the final standard.
