?? lint doesn't seem to catch type errors ??

why am not getting a type checking error?

let aaa: string = 151;

aaa = aaa[3];

console.log(aaa + 9);

let aaa: string = 151;

aaa = aaa[3];

console.log(aaa + 9);

let aaa: string = 151;

aaa = aaa[3];

console.log(aaa + 9);

let aaa: string = 151;

aaa = aaa[3];

console.log(aaa + 9);

I put the file in

/tmp

/tmp

/tmp

/tmp. There are not config files there.

% deno lint a.ts
Checked 1 file
deno run a.ts
NaN
