Bytes storage members

Push, index, and pop individual bytes in dynamic storage.

Why use this example

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

Solidity to run

bytes public data
data.push(0x12)
data.push(0x34)
bytes1 removed = data[data.length - 1]
data.pop()

removed
data.length
data[0]

Bytes members

What to expect

The removed byte remains 0x34 while the storage byte array shrinks to one item containing 0x12.

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.
