* getOrInsert is a helper function for maps that allows you to get a value
|
|
* from a map if it exists, or insert a new value if it doesn't. If it value doesn't
|
|
* exist, it will be computed by the provided function.
|
|
* @template K
|
|
* @template V
|
|
* @param {Map<K, V>} map The map object to check
|
|
* @param {K} key The key to check
|
|
* @param {() => V} computer function which will compute the value if it doesn't exist
|
|
* @returns {V} The value from the map, or the computed value
|
|
* @example
|
|
* ```js
|
|
* const map = new Map();
|
|
* const value = getOrInsert(map, "key", () => "value");
|
|
* console.log(value); // "value"
|
|
* ```
