javascript - I need to check for equality with a switch statement -

-

i'm writing hot or cold app. , need switch statement decide whether user hot or cold. here's code far: 

switch(true) {          	case (userguess / secretnumber === 1):          		setfeedback("you win");              	finish = true;              	break;              case ((userguess - secretnumber) > 50):              	setfeedback("you're ice cold!");              	break;              case ((userguess - secretnumber) > 30):              	setfeedback("you're cold!");              	break;              case ((userguess - secretnumber) > 20):              	setfeedback("you're warm!");              	break;              case ((userguess - secretnumber) > 10):              	setfeedback("you're hot!");              	break;              case ((userguess - secretnumber) > 0):              	setfeedback("you're blazing hot!");              	break;          }

edit: i'm trying replace following if/else statement switch. please tell me if it's possible , if so: how. here's old code: 

if (userguess / secretnumber === 1){              setfeedback("you win");              finish = true;            } else if ((secretnumber - userguess) > 60.5){              setfeedback("wow! freezing!");              } else if ((secretnumber - userguess) > 55.5){              setfeedback("wow! better put on jacket cause super cold!");              } else if ((secretnumber - userguess) > 50.5){              setfeedback("its super cold man!");              } else if ((secretnumber - userguess) > 40.5) {              setfeedback("now cold!");              } else if ((secretnumber - userguess) > 30.5) {              setfeedback("it's getting warm around here");              } else if((secretnumber - userguess) > 20.5) {              setfeedback("it's getting warm in here!");              } else if((secretnumber - userguess) > 15.5) {              setfeedback("it's getting very warm in here!");              } else if ((secretnumber - userguess) > 7.5){              setfeedback("it's hot!");              } else if ((secretnumber - userguess) > 5.5){              setfeedback("it hot here!");             } else if ((secretnumber - userguess) > 1.5){              setfeedback("i burning here!!");              } else if ((secretnumber - userguess) > 0.5){              setfeedback("its hotter sun!!!!!");          } else {          }

       int value = secretnumber-userguess;         if ((userguess / secretnumber) == 1)         {           setfeedback("you win");           finish = true;         }          else if (value > 60.5)           setfeedback("wow! freezing!");         else if (value > 55.5)           setfeedback("wow! better put on jacket cause super cold!");         else if (value > 50.5)           setfeedback("its super cold man!");         else if (value > 40.5)            setfeedback("now cold!");         else if (value > 30.5)            setfeedback("it's getting warm around here");         else if (value > 20.5)            setfeedback("it's getting warm in here!");         else if(value > 15.5)            setfeedback("it's getting very warm in here!");         else if (value > 7.5)           setfeedback("it's hot!");         else if (value > 5.5)           setfeedback("it hot here!");         else if (value > 1.5)           setfeedback("i burning here!!");         else if (value > 0.5)           setfeedback("its hotter sun!!!!!");      else {     }
