How can I print the output as

17 in 1 days

21 in 2 days

23 in 3 days

and not

17 in 0 days

21 in 1 days

23 in 2 days

const arr = [17, 21, 23];

const printForecase = function() {
    for (let i = 0; i < arr.length; i  ) {
        console.log(`${arr[i]} in ${i} days`);
    } } 
printForecase();

Since the index starts from 0, you just need to add one (1) when you print it in your console.log() (${i 1})

const arr = [17, 21, 23];

const printForecase = function() {
    for (let i = 0; i < arr.length; i  ) {
        console.log(`${arr[i]} in ${i 1} days`);
    } } 
printForecase();

You can just add 1 with {i}

const arr = [17, 21, 23];

const printForecase = function() {
for (let i = 0; i < arr.length; i  ) {
    console.log(`${arr[i]} in ${i 1} days`);
} } 
printForecase();

console.log(${arr[i]} in ${i 1} days)

1. Add 1 to the embedded expression ${i} so that it is ${i 1}

const arr = [17, 21, 23];

const printForecase = function() {
    for (let i = 0; i < arr.length; i  ) {
        console.log(`${arr[i]} in ${i 1} days`);
    } } 
printForecase();
