 By default `ts-jest` uses TypeScript `LanguageService` API in the context of a project (yours), with full type-checking and features.
-But TypeScript `Program` can also be used to achieve the same behavior as `LanguageService`.
+But TypeScript `Incremental Program` can also be used to achieve the same behavior as `LanguageService`.
 That's what the `compilerHost` option (which defaults to `false`) does.
 
-There are 2 types of TypeScript `Program`, one is `Incremental Program` which is only available from TypeScript 3.4
