How do I use comparison operators in a switch?

  How to use & lt; = in a switch?
  Here's my example:
  

  switch (элемент.value.length) {
  
    case >=5:
      // code
  }

  
  In general, how to substitute & gt; = for 5?

  You shouldn't do this in switch, it's for exact values. You should use logical operators in if - this is more correct and much faster. Well, so

  const num = 10;
  
  
  
  switch (true) {
  
    case (num <= 5):
  
      console.log('Num меньше или равна 5')
  
      break;
  
    case (num >= 5):
  
      console.log('Num больше или равно 5')
  
      break;
  
    default:
  
      console.log('Num не известно')
  
  }
  
  // Num больше или равно 5

  
  
  Shit code! Do not repeat!

  No way. case takes a ready-made expression, not a part of it, in which case "& gt; = 5" is missing an operand on the left
  
  
  
  Use "if" to compare other than "=="
