詳細を表示 SyntaxError: Applying delete to unqualified name in strict modeThe delete operator was used on a plain variable name in strict mode, which is not allowed.
In strict mode, you cannot use delete on a variable, function argument, or function name. The delete operator is only for removing object properties, not for deleting variables.
Use delete only on object properties: delete obj.prop. To 'remove' a variable, set it to undefined or null. If you need to remove a global, use delete globalThis.name instead of delete name.
