  Executes action for each element. Safe if null.

• void Times(this int count, Action<int> action)
  Executes action count times. Safe if null.

• bool IsEmpty(this IEnumerable value) – Checks if empty

• bool IsNotEmpty(this IEnumerable value) – Checks if not empty

• bool IsNullOrEmpty(this IEnumerable value) – Checks null or empty

• bool IsNotNullOrEmpty(this IEnumerable value) – Checks not null and not empty

• T Pop<T>(this IList<T> source) – Returns last element and removes it

• T Shift<T>(this IList<T> source) – Returns first element and removes it

• void Unshift<T>(this IList<T> source, T toAdd) – Adds element at first position

• T AnyOne<T>(this IEnumerable<T> source) – Returns any element (throws if null/empty)

• bool None<T>(this IEnumerable<T> source, Func<T, bool> predicate = null) – Checks if no elements match the predicate

🔍 Object Comparison

• void EqualJsonCheck(this object obj, object toCompare)
  Compares objects via JSON serialization and throws if unequal.

• bool IsEqualJson(this object obj, object toCompare)

✏️ String Utilities

• string ExpEnv(this string text) – Shortcut for Environment.ExpandEnvironmentVariables
• string UseFormat(this string text, params string[] @params) – Uses string.Format for placeholders
