While and do-while loops

Why use this example

Use this pattern to isolate Solidity branching, looping, assignment, and function-call syntax before combining it with contract state. The entry isolates while and do-while loops so its input, result, and state changes stay easy to compare.

Solidity to run

uint256 value = 0
while (value < 3) {
  value++
}
do {
  value--
} while (value > 1)
value

Official Solidity reference

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

What to expect

The while loop raises the value to 3, then the do-while loop lowers it until the final value is 1.

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.
