Which of the following is a common Jest matcher used to check if a value is truthy?
- toBeNull
- toBeTruthy
- toBeFalsy
- toEqual
The common Jest matcher used to check if a value is truthy is toBeTruthy. This matcher checks if a given value evaluates to true in a boolean context. It's often used to ensure that a value is not null, undefined, false, 0, NaN, or an empty string. The other options (toBeNull, toBeFalsy, and toEqual) perform different comparison operations and do not specifically check for truthiness.
