The condition if('0') will evaluate to true. The string '0', despite containing the character that represents the falsy number 0, is a non-empty string. In JavaScript, all non-empty strings are truthy values. When used in a conditional context like an if statement, JavaScript implicitly converts the value to a boolean. Since '0' is a non-empty string, it's converted to true, and the if block is executed. This is a common source of confusion, especially when working with form inputs where a user might enter '0' as text.
