Typescript error:- Property 'forEach' does not exist on type 'string'

Question

whenever i used forEach() i got this error in terminal

[ts] Property 'forEach' does not exist on type 'string'.

My application works in browser properly. Everything works properly but i don't want such errors in terminal.

I used below code for it. Please suggest me what i missing.

 job.forEach(function(state) {
        if((totalcarer['userId']+"")===state.rNo)
        {
          cjobState = state.cJobstatus;
        }
      });

Answer 1

arrays: string[];
arrayString: string;

See the diff between? one is array and another is string.

arrays.forEach(...) // valid.
arrayString.forEach(...) //invalid.
