当我在 Repl.it 软件中运行我的代码时，它无法识别我的任何变量

Question

I think my code is ok, but every time I get an unexpected token error. I am writing in Javascript (I am also brand new to it). I really need some help and it would be greatly appreciated:) A snippet of the code:

function isitSublimeString(theString)
  var listaAlpha = 'abcdefghijklmnopqrstuvwxyz'        
        let lista = sorted(list(theString.toLowerCase()))
        let count = [1]
        let word = 0
        if (lista[0] != 'a');
              {return False}
        var i;

Answer 1

Functions need curly braces:

function isitSublimeString(theString)**{**
  var listaAlpha = 'abcdefghijklmnopqrstuvwxyz'        
        let lista = sorted(list(theString.toLowerCase()))
        let count = [1]
        let word = 0
        if (lista[0] != 'a');
              {return False}
        var i;

**}**
