Mutating Methods (modify original array):

• push() - adds to end
• pop() - removes from end
• unshift() - adds to beginning
• shift() - removes from beginning
• splice() - adds/removes elements anywhere
• reverse() - reverses array
• sort() - sorts array
• fill() - fills elements with value

Methods thêm/xóa ở đầu/cuối: Thêm (push, unshift) → return độ dài mới Xóa (pop, shift) → return phần tử bị xóa Method thêm/xóa ở giữa: splice → return mảng các phần tử bị xóa Methods biến đổi toàn bộ mảng: reverse, sort, fill → return chính mảng đã biến đổi

Non-Mutating Methods (return new array, original unchanged):

map() - transforms elements filter() - filters elements concat() - combines arrays slice() - extracts portion of array join() - creates string from array reduce() - reduces to single value forEach() - just loops, returns nothing indexOf() - finds index includes() - checks if element exists find() - finds element findIndex() - finds element index some() - checks if some pass test every() - checks if all pass test
