Nested 'If' vs. Guard Condition - Guard Clauses Technique

Показать описание

Guard clauses are a technique that focuses on the fast fail or guards' first approach to stop execution as early as possible.

“In computer programming, a guard is a boolean expression that must evaluate to true if the program execution is to continue in the branch in question. Regardless of which programming language is used, guard code or a guard clause is a check of integrity preconditions used to avoid errors during execution.” — Wikipedia.

I actually used this more as a test tutorial, then guard conditions tutorial, I've always felt testing was so mysterious, but seems really simple, thank you!
