Description
Add
@typescript-eslint/no-unused-expressionsto typescript config.In v46:
no-unused-expressionsno-unused-expressionsand enabling@babel/no-unused-expressions.no-unused-expressions to offbut left@babel/no-unused-expressionsenabled - which seems like an oversight given that@typescript-eslint/no-unused-expressionsexisted.In v47.0.0 we removed configuration of
@babel/no-unused-expressionsentirely, which meant that there was no linting of unused-expressions in typescript files. This change brings back unused expression linting to typescript files.
