Complexity

Examples of O(1)

• Accessing the length of an array
• Modulo Operator
• Setting/Accessing object values

Examples of O(n)

• Iterating over elements in an array
• .find(), .map(), .filter()
• ===, iterates over each char to check equality

Examples of O(n^2)

• Nested for loop
• Assigning new values inside a for loop
• === inside a for loop: iterates over each char to check equality of each char
