Storage array push and pop

Why use this example

Use this pattern to explore how Solidity represents typed values and how state-changing expressions affect storage. The entry isolates storage array push and pop so its input, result, and state changes stay easy to compare.

Solidity to run

uint256[] public values
values.push(10)
values.push() = 20
uint256 removed = values[1]
values.pop()

removed
values.length
values[0]

Official Solidity reference

Compare this focused investigation with the complete language definition in the Solidity documentation.

What to expect

The removed value remains 20 while the storage array shrinks to one item containing 10.

Continue the investigation

Change a value, add another expression, or open Inspect after the run. Accepted entries remain available to the next entry, and the clean replay keeps the complete result reproducible.
