Dictionaries

dict<T> maps string keys to values of one type. It stores content in an NBT compound.

func main() {
    var rewards: dict<int> = {daily: 10, weekly: 50}
    rewards["bonus"] = 5

    if rewards.containsKey("daily") {
        print(rewards["daily"])
    }

    rewards.remove("weekly")
    print(rewards.size())
}

Literal keys are identifiers. Indices and methods receive string keys.

Method	Purpose
`containsKey(key)`	Test whether a key exists
`remove(key)`	Remove a key and value
`merge(other)`	Merge another dictionary
`size()`	Read the number of entries
`isEmpty()`	Test whether the dictionary is empty
`clear()`	Remove all entries

Establish that a key exists before reading it. Use Map to iterate over keys. Use data templates for fixed fields.
