{
"rules": {
"@typescript-eslint/no-use-before-define": ["error"]
}
}const updatedAt = data?.updatedAt;
// ^^^^^^^^^
// 'updatedAt' was used before it was defined. (@typescript-eslint/no-use-before-define)Expected Result
Would not produce any errors.
Actual Result
Produces an error:
// 'updatedAt' was used before it was defined. (@typescript-eslint/no-use-before-define)Additional Info
This issue seems to only happen when the variable name is the same as the property name. For instance, the code below does not show the warning:
const timestamp = data?.updatedAt;Versions
