If you add in the end, the most the most simple you just need to do processing of the parameter for into good, of course, if you are in front of the parameter is also optional parameters, the judgment more

Only need to add at the end of the parameters for processing, behind only refer to the function of the place will use this parameter, the used no matter before,
My question is if you added a parameter function here into the function (a, b), call the place is still a function (a), will have a problem,

CodePudding user response:

No problem, before the call just reads the parameter a, add parameters used after ok, as long as he doesn't pass b alone actually use {} is more convenient to expand function parameters, need to add fields on the attribute to add
