Map Module

The map module provides utilities for map (dictionary) operations.

Functions

map.containsKey<K, V>(m: map[K]V, key: K) -> Boolean

Checks if the map contains the specified key.

import map
let m: map[String]Number = {}
m["a"] = 1
map.containsKey(m, "a") # true

map.delete<K, V>(m: map[K]V, key: K) -> map[K]V

Returns a new map with the specified key removed.

import map
let m: map[String]Number = {}
m["a"] = 1
m = map.delete(m, "a")
