ts/no-ts-ignore

Dlaczego

@ts-ignore hides every error on the next line, including the new ones a later change introduces, and stays forever after the original problem is fixed. @ts-nocheck does the same for a whole file. Nobody knows why it is there or whether it is still needed.

Poprawka

Fix the type. When that is not possible today, use // @ts-expect-error <why, and when it can go>: it hides the error and itself fails as soon as the error disappears, so it is removed on time.

Przykłady

// bad
// @ts-ignore
chart.render(data)
// good
// @ts-expect-error chart.js 4 types lack the plugin option; remove after upgrading to 5
chart.render(data, { plugins })
