Configuration Objects
Passing a large number of parameters is not convenient. A better approach is to substitute all the parameters with only one and make it an object.
var conf = { username: "batman", first: "Bruce", last: "Wayne" };addPerson(conf);
Pros
Cons
• No need to remember the parameters and their order
• You can safely skip optional parameters
• Easier to read and maintain
• Easier to add and remove parameters
• You need to remember the names of the parameters
• Property names cannot be minified
This pattern could be useful when your function creates DOM elements.
