ReferenceError: Invalid left-hand side in assignment

Was verursacht diesen Fehler

You tried to assign a value to something that is not a valid assignment target, such as a literal (5 = x), a function call result, or using = instead of == in a conditional expression.

So beheben Sie ihn

Check that the left side of the assignment is a variable, property, or destructuring pattern. If you meant comparison, use === instead of =. Verify you are not accidentally assigning to a function call.

5 = x; // ReferenceError: Invalid left-hand side in assignment
