What am I doing wrong here? tempRating is always 'hot'

const temp = 10; //r.data.weatherData.temp;
console.log({ temp });
switch (temp) {
    case temp <= 30:
            setTempRating('cold');
            break;
    case temp <= 50:
        setTempRating('cool');
        break;
    case temp <= 70:
        setTempRating('warm');
        break;
    default:
        setTempRating('hot');
        break;
}

const temp = 10; //r.data.weatherData.temp;
console.log({ temp });
switch (temp) {
    case temp <= 30:
            setTempRating('cold');
            break;
    case temp <= 50:
        setTempRating('cool');
        break;
    case temp <= 70:
        setTempRating('warm');
        break;
    default:
        setTempRating('hot');
        break;
}

can you show the error

dmikester1•15mo ago

there is no error, tempRating gets set to 'hot' on every run based on a 'temp' value of 10, it should be getting set to 'cold'

instead try doing this with if else statement, instead of switch case. Above is also the reason why only default case is running.

what is the reason why only default case is running?

NishantJoshi•15mo ago

well if you want to run it do one thing do switch(true){ // your code } const temp = 10; function setTempRating(val) { console.log(temp is ${val}); } switch (true) { case temp <= 30: setTempRating("cold"); // console.log("first" + temp); break; case temp <= 50: setTempRating("cool"); // console.log("second" + temp); break; case temp <= 70: setTempRating("warm"); // console.log("third" + temp); break; default: setTempRating("hot"); break; }

JavaScript: using a condition in switch case

How can I use a condition inside a switch statement for JavaScript? In the example below, a case should match when the variable liCount is <= 5 and > 0; however, my code does not work: switch (

check this out... you will understand the concept, and why your code was not working

The reason why default case is always executed is because temp is compared to each case expression, e.g. temp === (temp <= 10) - > temp === true -> false. Every case condition is evaluated first (returning true, cause 10 is less than every number compared in there) and then 10 is compared to true, which gives false, so default is matched
