Where is the error in the switch case?

Question

JavaScript

I downloaded a new (maybe not new) course from Udemy and I do it exactly as in the lecture, but either an error falls out or I don’t understand what it is.
Here is js:

let num = 50;

switch (num) {
    case num > 60:
         console.log("Нет, переменная меньше 60");
         break;
    case num < 40:
         console.log("Нет, переменная больше 40");
         break;
    case num == 50:
         console.log("Да, переменная ровна 50");
         break;
}

This is what makes JavaScript (ES6) code snippets not work

How to deal with it?

Answer 1

The switch uses the strict === comparison, change the condition to switch(true) as the result of your comparisons will be true/false.
