This video explains how to write an if / else conditional statement in Solidity. Most of the control structures known from curly-brace languages are available in Solidity.

There is: if, else, while, do, for, break, continue, return, with the usual semantics known from C or JavaScript.

Solidity also supports exception handling in the form of try/catch-statements, but only for external function calls and contract creation calls. Errors can be created using the revert statement.

Parentheses cannot be omitted for conditionals, but curly braces can be omitted around single-statement bodies.

Note that there is no type conversion from non-boolean to boolean types as there is in C and JavaScript, so if (1) { ... } is not valid in Solidity.

There is also a shorthand way to write conditional statements using ternary operators.
