access native js global object in angular4 or exclude single typescript line from compiling?

Question

In ts I would like to keep a single line of Javascript code native as it is, because it uses a type, which is not known to the tsc (no node_module available) but at runtime it exists in global window object from browser. Is there an easy solution? (by annotation i.e.). I use angular4.

Answer 1

Use the any type if you do not know its type.

const foo: any = window.globalVar

or

const foo = windows.globalVar as any
