TypeTags .WeakRef

Overview#

A WeakRef object lets you hold a weak reference to another object, without preventing that object from getting garbage-collected.

Usage#

import { TypeTags } from 'typetags'

class Counter {
  constructor(element = 0) {
    this.ref = new WeakRef(element)
    this.start()
  }

  static getRefType() {
    return TypeTags.get(this.ref)
  }
}

TypeTags.WeakRef === Counter.getRefType()
// → true

console.log(TypeTags.WeakRef)
// → [object WeakRef]
