WeakMap Basics Lab
WeakMaps are a special type of Map that allows garbage collection of keys. They only hold weakly referenced keys, allowing their values to be garbage collected if there are no other references to the key objects. This can be helpful when working with large datasets or in memory-sensitive environments.
Key concepts learned in this lab:
- Creating WeakMap instances
- Adding key-value pairs to WeakMap
- Accessing values using keys
- Deleting keys from WeakMap
Remember to always refer to the MDN documentation for syntax and usage information: WeakMap
