Ignore a "error TS2683: 'this' implicitly has type 'any' because it does not have a type annotation."

I wanted to have shared utility function for dumping many scattered objects in the code like below, but it generates a TypeScript error. Is there any way to do this without repeating the shared code? I tried this and this. It seems to work fine in Chrome browser JS.

function formatthis() { return JSON.stringify(this); }
...
function whatever() {
  ...
  var something = { aa:234, bb:123, toString:formatthis };
  ...
  var something2 = { dfwerg:22, wer:11, toString:formatthis };
  ...
  var something3 = { sergw:55, qsfds:33, toString:formatthis };
  ...
  console.log('looks like '+something);
  ...
}

UPDATE: Example updated to stress reuse of method(s) among different random objects. It appears to work in Chrome browser (globally, in functions, with "use strict", etc), but // @ts-ignore always compiles but does not always work in Node, not sure why.

As other commenters have suggested, rather than ignoring the issue, you should declare this as a parameter of your function. Something like:

function formatthis(this: unknown) {
  return JSON.stringify(this);
}
