Despite your best intentions, the any type can sometimes leak into your codebase. Returning an an any-typed value from a function creates a potential type safety hole and source of bugs in your codebase.

If aPromise<any> value is returned, the any type can leak into your code.

declareconstpromise:Promise<any>;constbaz=async()=>promise;functionaddOne(num:number){returnnum+1;}(async()=>{addOne(awaitbaz());// no type error});

Fail

declareconstpromise:Promise<any>;constfoo=()=>promise;constbar=async()=>promise;// ...

Pass

declareconstpromise:Promise<number>;constfoo=()=>promise;
