How to use Function constructor ? [Solved]

Question

In the following code , the first compile one works as expected but second doesn't , why so?

----------------------------
var compile=new Function("data",'return ""+data.abc')

console.log(compile(abc));

compile=new Function("data",'return re()');

console.log(compile(abc))
----------------------

re function returns same string as we have in first compile , i. e. ""+data.abc .

So my question is ,does re function returns ""+data.abc or """+data.abc", if it's the former one than it should work well but if it's the latter than it doesn't and so what should i do ? Ty!

Here is the code,

Edit: ok , it works fine for just {{abc}}, after adding the string returned by re to return but then again it fails for something like {{abc}} world.

Ty everyone for your time!

I was playing with first compile sentence to see how should i structure it to output "hello world hello" And so this is what i did ,

var compile=new Function("data",'return ""+data.abc + " world " + data.abc')

well this gave me an idea to add double quotes around the actual strings like "world" And so i fixed fnStr+=`+${t}` as fnStr+=`+"${t}"`.
