<K>(key: K): <V>(self: MutableHashMap<K, V>) => Option.Option<V>
<K, V>(self: MutableHashMap<K, V>, key: K): Option.Option<V>Looks up a key in the MutableHashMap safely.
When to use
Use to safely read a MutableHashMap value for a key as an Option.
Details
Returns Some(value) when an equal key is present and None when the key is
absent.
Example (Getting a value)
import { MutableHashMap } from "effect"
const map = MutableHashMap.make(["key1", 42], ["key2", 100])
console.log(MutableHashMap.get(map, "key1")) // Some(42)
console.log(MutableHashMap.get(map, "key3")) // None
// Pipe-able version
const getValue = MutableHashMap.get("key1")
console.log(getValue(map)) // Some(42)export const const get: {
<K>(key: K): <V>(
self: MutableHashMap<K, V>
) => Option.Option<V>

interface MutableHashMap<out K, out V>A mutable hash map that stores key-value pairs and supports both referential
and Effect structural equality.
When to use
Use as a mutable key-value map when in-place updates are acceptable and keys
may rely on Effect structural equality.
Details
Operations mutate the map in place. Keys that implement Equal / Hash can
be looked up structurally; other keys use normal JavaScript reference or
primitive equality.
Example (Using a mutable hash map)
import { MutableHashMap } from "effect"
// Create a mutable hash map with string keys and number values
const map: MutableHashMap.MutableHashMap<string, number> = MutableHashMap
.empty()
// Add some data
MutableHashMap.set(map, "count", 42)
MutableHashMap.set(map, "total", 100)
// Use as iterable
for (const [key, value] of map) {
console.log(`${key}: ${value}`)
}
// Output:
// count: 42
// total: 100
// Convert to array
const entries = Array.from(map)
console.log(entries) // [["count", 42], ["total", 100]]
