WebOct 12, 2015 · When JavaScript stops evaluating the operands of the AND operator, that's called short-circuiting. The Anti-Pattern. Short-circuiting is a useful behavior to avoid unnecessary computations. However, it can be misused to create the same behavior as an if statement. Take this example: hasUserId && logUserIn(); It's equivalent to this if statement: WebPython always evaluates the left operand before the right- even in function arguments.
