[JS] Deconstruct Assignemnt Example

This example shows that how to use deconstucting assignment with some function parameters.

The old way you must provide the parameters in orders.

// Static assignment
function ajax(title, url, params, onSuccess, onFail, onCallback) {
  console.log(title, url, params, onSuccess, onFail, onCallback);
}

ajax("selectSome", "/data/selectSome", "", "", function () {});

With deconstructing assignment, you do not need to worry about the ordering of parameters. If the name is matched then will assign to the value.

// New with destrucuring
function ajax2({ title, url, params, onSuccess, onFail, onCallback }) {
  console.log(title, url, params, onSuccess, onFail, onCallback);
  onSuccess();
  onCallback();
}

// Use it
let request = {
  url: "/data/update",
  title: "update",
  onCallback: () => {
    console.log("Callback Function");
  },  
  onSuccess: () => {
    console.log("Successful!");
  },
};

// Run
ajax2(request);
