You can't. This is an open issue in TypeScript.

You can't.

As a workaround you can use a // @ts-nocheck comment at the top of a file to disable type-checking for that file: https://devblogs.microsoft.com/typescript/announcing-typescript-3-7-beta/

So to disable checking for a block (function, class, etc.), you can move it into its own file, then use the comment/flag above. (This isn't as flexible as block-based disabling of course, but it's the best option available at the moment.)

If you don't need typesafe, just bring block to a new separated file and change the extension to .js,.jsx

There is

// @ts-nocheck

It can be added at the beginning of the file and all errors in it will be ignored, isn't the block specific answer you are looking for but in some scenarios it is equivalent.

https://devblogs.microsoft.com/typescript/announcing-typescript-3-7/#ts-nocheck-in-typescript-files

you can use // @ts-expect-error to suppress the error on one line, and you can do it for multiple lines ( a bit cumbersome)

https://www.typescriptlang.org/docs/handbook/release-notes/typescript-3-9.html#-ts-expect-error-comments

BUT WAIT

if you use // @ts-expect-error on line that has no error, it will result in error Unused '@ts-expect-error' directive.

so make sure to only use it on line that has type error

If you are using prettier you can add //prettier-ignore for code that is small enough that prettier just turned into more than one line
