Today, we will be learning about Redis' second data structure, which is the `list`. #thread 🧵

`List`: are like an array but we can use the list as a stack that follows Last-In-First-Out(LIFO) principle and a queue that follows First-In-First-Out (FIFO) principle

In this example, we gonna add users to our beta_list to send invitations in the near future

In the list, we use the push command, and to remove an item, we use the pop command. However, it's important to note that there are different types of push and pop commands available

LPUSH -> pushes the item to the left side/top of the list

LRANGE -> to view items within a range, pass the start and end index values as parameters

LPOP -> removes an item from the left side/top of a list

RPUSH -> push an item to the right side/bottom of the list

RPOP -> remove an item from the right side/bottom of a list

LLEN -> to view the size of the list

LTRIM -> keeps the data from start and end offset index value in the list and deletes others

Bonus:
Combine LPUSH and LPOP the list becomes a stack
Combine RPUSH and LPOP the list becomes a queue

The list can hold 4 billion entries (2^32)
Performance:
LPOP, LPUSH, RPUSH -> O(1)
LRANGE ->O(s+n) n- length of list and s is the start offset
