TypeScript: Property does not exist on type '{}'

Question

I am using Visual Studio 2013 fully patched. I am trying to use JQuery, JQueryUI and JSRender. I am also trying to use TypeScript. In the ts file I\'m getting an error as follo

Answer 1

Access the field with array notation to avoid strict type checking on single field:

data['propertyName']; //will work even if data has not declared propertyName

---

Alternative way is (un)cast the variable for single access:

(data).propertyName;//access propertyName like if data has no type

The first is shorter, the second is more explicit about type (un)casting

---

You can also totally disable type checking on all variable fields:

let untypedVariable:any= {}; //disable type checking while declaring the variable
untypedVariable.propertyName = anyValue; //any field in untypedVariable is assignable and readable without type checking

Note: This would be more dangerous than avoid type checking just for a single field access, since all consecutive accesses on all fields are untyped
