JSLint : Expected '!!' and instead saw '?'

问题

I am getting the error in the question mark. Here is the code

var isParallelStage = ($("#workflowStagesList .workflowStageListItemActive").find("p").text() === "P") ? true : false;

Error:

JSLint : Expected '!!' and instead saw '?'.

回答1:

? true : false is an antipattern - it's totally useless, an identity function, you can simply omit it, you've already got a boolean. And if you didn't, you should use !! or Boolean(…) to cast your value to a boolean.
