What is the difference between if and require statement in solidity

Question

if() and require() both have condition based execution, they both require some condition before execution, so can they be used interchangeably??

Answer 1

If() and require() have separate functions and cannot be used interchangeably.

if(): when the first condition becomes false the next condition i.e else block gets executed.

require(): it has a diffrent function. It is actually an error handling statement, and when the require condition is false, the execution stops and the transaction gets rolled back.
