If and else branches

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 if and else branches so its input, result, and state changes stay easy to compare.

Solidity to run

function classify(uint256 value) public pure returns (uint256) {
  if (value < 10) return 1;
  else if (value < 100) return 2;
  else return 3;
}

classify(7)
classify(42)
classify(420)

Official Solidity reference

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

What to expect

The three calls take the first, second, and final branch and return 1, 2, and 3 respectively.

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.
