types typescript inside for loop local loop variable not respecting type

Question

this.venuelist has type Venue

venuelist:Venue[] = [];

Type

Venue

has the property

neighborhood

on it.

I have the following for loop

for(let venue in this.venuelist){

      let remove = false;

      if(this.filters.neighborhood != ''){

        if(venue.neighborhood != this.filters.neighborhood){

          remove = true;

        }

      }

    }



calling venue.neighborhood called in the second `if statement` is not working

the error is: Property 'neighborhood' does not exist on type 'string.

for why? Why must it do this. Why can't it play nice? How do I make it place nice?
