Your function should ideally be returning a value.
Use map to iterate over the array, create a new array of strings, and join that up into a new string before you return it.
const arr1 = [17, 21, 34];
function getForecast(arr1) {
return arr1.map((num, i) => {
return `${num} C on day ${i + 1}`;
}).join(', ');
};
console.log(getForecast(arr1));Construct the string inside the loop. Assign it to a variable and then print it outside the for loop.
const arr1 = [17, 21, 34];
const printForecast = function(arr1) {
let string = "";
for (var i = 0; i < arr1.length; i++) {
string += `${arr1[i]} C on day ${arr1.indexOf(arr1[i]) + 1}, `;
}
console.log(string);
};
printForecast(arr1);const arr1 = [17, 21, 34];
arr1.forEach((item, index) => {
console.log(`${item} C on day ${index + 1}`);
});
