//#region src/map/forEach.ts
/**
* Executes a provided function once for each entry in a Map.
*
* This function iterates through all entries of the Map and executes the callback function
* for each entry. The callback receives the value, key, and the Map itself as arguments.
*
* @template K - The type of keys in the Map.
* @template V - The type of values in the Map.
* @param map - The Map to iterate over.
* @param callback - A function to execute for each entry.
*
* @example
* const map = new Map([
*   ['a', 1],
*   ['b', 2],
*   ['c', 3]
* ]);
* forEach(map, (value, key) => {
*   console.log(`${key}: ${value}`);
* });
* // Output:
* // a: 1
* // b: 2
* // c: 3
