+* Checks if a given value is empty.
+*
+* - If the given value is a string, checks if it is an empty string.
+* - If the given value is an array, `Map`, or `Set`, checks if its size is 0.
+* - If the given value is an [array-like object](../predicate/isArrayLike.md), checks if its length is 0.
+* - If the given value is an object, checks if it is an empty object with no properties.
+* - Primitive values (booleans, numbers, or bigints) are considered empty.
+*
+* @param [value] - The value to check.
+* @returns `true` if the value is empty, `false` otherwise.
+*
+* @example
+* isEmpty(); // true
+* isEmpty(null); // true
+* isEmpty(""); // true
+* isEmpty([]); // true
+* isEmpty({}); // true
+* isEmpty(new Map()); // true
+* isEmpty(new Set()); // true
+* isEmpty("hello"); // false
+* isEmpty([1, 2, 3]); // false
+* isEmpty({ a: 1 }); // false
+* isEmpty(new Map([["key", "value"]])); // false
+* isEmpty(new Set([1, 2, 3])); // false
