I have to convert temperature in javascript
So I made the first for loop to console all the fahrenheit temps, I then created a function to convert fToC. It all works and I get my results but is there a way to loop the long console log to convert fToC?
for (let fahrenheit = 20; fahrenheit <= 120; fahrenheit = fahrenheit + 5) {
console.log(fahrenheit);
}
function ftoC(fahrenheit) {
let celcius = (fahrenheit - 32) / 1.8;
return celcius;
}
console.log(ftoC(20));
console.log(ftoC(25));
console.log(ftoC(30));
console.log(ftoC(35));
console.log(ftoC(40));
console.log(ftoC(45));
console.log(ftoC(50));
console.log(ftoC(55));
console.log(ftoC(60));
console.log(ftoC(65));
console.log(ftoC(70));
console.log(ftoC(75));
console.log(ftoC(80));
console.log(ftoC(85));
console.log(ftoC(90));
console.log(ftoC(95));
console.log(ftoC(100));
console.log(ftoC(105));
console.log(ftoC(110));
console.log(ftoC(115));
console.log(ftoC(120));Since it's incrementing by a fixed number, there's a very simple loop you could use. Here's a for:
const min = 20;
const max = 120;
for(let i = min; i <= max; i+=5)
{
console.log(ftoC(i));
}
Or a while:
let i = 20;
const max = 120;
while(i <= max)
{
console.log(ftoC(i));
i += 5;
}
A bit more modern version
const ftoC = fahrenheit => ((fahrenheit - 32) / 1.8).toFixed(2);
const pad = (num,spaces) => (""+num).padStart(spaces," ");
const res = [];
[...Array(141).keys()] // create an array from 0-141
.slice(20) // chop the first 20
.forEach((_,i) => { if (i%5 === 0) res.push(`${pad(i,3)}C: ${pad(ftoC(i),6)}F`) // save if i modulo 5 is 0
});
document.querySelector('pre').innerHTML = res.join('<br/>')<pre></pre>
