Protractor Memo - treat array, sorting check

Leaving a memo

customerNameList()      {return element.all(by.css("#items")).
all(by.css(".list-item-title"));} 

This customerNameList() fetches customer name list data.

 step.Then(/^Check sorting$/,  (done: Callback)=> {
   let sorted = [] , unSorted = [];
   let cName = customerViewPage.customerNameList();

   cName.map(function(eachName){
     return eachName.getText().then(function(unSorted){
       return unSorted;
     });
   }).then(function(unSorted){
     let sorted = unSorted.slice();
     sorted = sorted.sort(); //sort the array
     for(let i = 0; i < sorted.length; i++){
       console.log(' Array1  : ' + sorted[i] + 
'  is equals to Array2 : ' + unSorted[i]);
       expect(sorted[i]).is.equal(unSorted[i]);
     }
     done();
   });
 });

Check sorting results.
unSorted[] array will have current customer name list.
sorted[] array is sorting the current customer name list.

compare sorted[] and unSorted[]
if pass then the customer list is sorted properly.

step.Then(/^Check sorting$/,  (done: Callback)=> {
  let sorted = [] , unSorted = [];
  let cName = customerViewPage.customerNameList();
  let i = 0;
  cName.each(function(eachName){
    eachName.getText().then(function(name){
      // unSorted[i] = name.toLowerCase();
      unSorted[i] = name;
      i++;
    });
  }).then(function(){
    sorted = unSorted.slice();
    sorted.sort();
    for(let i = 0; i < sorted.length; i++){
      console.log(' Array1  : ' + sorted[i] + 
'  is equals to Array2 : ' + unSorted[i]);
      expect(sorted[i]).is.equal(unSorted[i]);
    }
    done();
  });
});

This step has the same functionality as above.

let statelist:any;
 let sortedStatelist:any;
 addCustomerPage.state().click().then(()=>{
   addCustomerPage.stateDropDownOptions().then(function (actualListOfStates) {
     statelist=actualListOfStates.slice();
     sortedStatelist=statelist.sort();
     // expect(statelist).to.contains(sortedStatelist);
     for(let i=0;i<sortedStatelist.length;i++){
       expect(statelist[i]).is.equal(sortedStatelist[i]);
     }
     done();
   })
 })

Fetch items from dropdown menu and check sorting status.

JavaScript Array slice() Method

var fruits = ["Banana", "Orange", "Lemon", "Apple", "Mango"];
var citrus = fruits.slice(1, 3);

Orange,Lemon

Definition and Usage

The slice() method returns the selected elements in an array, as a new array object.

The slice() method selects the elements starting at the given start argument, and ends at, but does not include, the given end argument.

Note: The original array will not be changed.
