//#region src/predicate/isMap.ts
/**
* Checks if a given value is `Map`.
*
* This function can also serve as a type predicate in TypeScript, narrowing the type of the argument to `Map`.
*
* @param value The value to check if it is a `Map`.
* @returns Returns `true` if `value` is a `Map`, else `false`.
*
* @example
* const value1 = new Map();
* const value2 = new Set();
* const value3 = new WeakMap();
*
* console.log(isMap(value1)); // true
* console.log(isMap(value2)); // false
* console.log(isMap(value3)); // false
