How to use `@ts-ignore` for a block?
TypescriptTslintTypescript Problem Overview
The // @ts-ignore comment enables the TypeScript compiler to ignore the line below it.
How can one ignore a whole block of code with TypeScript?
Typescript Solutions
Solution 1 - Typescript
You can't. This is an open issue in TypeScript.
Solution 2 - 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.)
Solution 3 - Typescript
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.

Solution 4 - Typescript
You can use //@ts-nocheck at the top of the file Files
reference: Ignore all errors in a typescript file
Solution 5 - Typescript
you can use // @ts-expect-error to suppress the error on one line, and you can do it for multiple lines ( a bit cumbersome)
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
Solution 6 - Typescript
Just use
// @ts-ignore-start
typescript is ...
// @ts-ignore-end
Solution 7 - Typescript
If your goal is to ignore some method or property only in the declaration output you can use the internal annotation to do that.
Leaving this here as since this post is the top search result and I came across while searching for a way to ignore things in the declaration output.
Solution 8 - Typescript
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
Solution 9 - Typescript
If you don't need typesafe, just bring block to a new separated file and change the extension to .js,.jsx
