Pass object parameters instead of an overly long parameter list

If the function parameters are too long, it will increase the risk of error. It is troublesome to ensure that the order of transmission is correct, and the readability of the code will become worse. Try to ensure that the parameters of the function will not be too long. If more than one parameter must be passed, it is recommended to use an object instead.

Generally speaking, it is best to have no more than 3 function parameters.

Function setUserInfo (id, name, address, sex, mobile, qq) {console.log ('id=' + id); console.log ('name=' + name); console.log ('address=' + address); console.log ('sex=' + sex); console.log ('mobile=' + mobile); console.log ('qq=' + qq);}; setUserInfo (1314, 'sven',' shenzhen', 'male',' 137 examples, 377876679) Function setUserInfo (obj) {console.log ('id=' + obj.id); console.log ('name=' + obj.name); console.log ('address=' + obj.address); console.log ('sex=' + obj.sex); console.log ('mobile=' + obj.mobile); console.log ('qq=' + obj.qq);} SetUserInfo ({id: 1314, name: 'sven', address:' shenzhen', sex: 'male', mobile:' 137 arguments, qq: 377876679}); the above is all the content of the article "how to pass object parameters instead of too long parameter lists".
