+ * 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 {function(): 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"
+ * ```
