Example I have an array

`all_object = ['A', 'B', 'C']`

and I want to create a string from this array is

`"stringANDstringANDstring"`

if `all_object = ['A', 'B', 'C','D']`

it will become

`"stringANDstringANDstringANDstring"`

may I know how does I archive this?

There is no A or B or C in result? Only string AND string? I think you are looking how to join array elements  
See this to find how to ... [Array.prototype.join() - JavaScript | MDN](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/join)

Ohh fully understood right now! thanks you very much!  
I loop first

```auto
    for (i = 0; i < all_object.length; i++) {
        newObject.push(textString);
    }

```

`newObject= newObject.join("AND");`

and everything done!

You don't need the loop, just  
`newObject= all\_object.join("AND")

That will not affect all\_object
