数组打印元素索引 0 作为索引 1

Question

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();

Answer 1

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();

Answer 2

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 )

Answer 3

const arr = [17,21,23];
const printForecase = ()=>{
        let days = 1;
        for(let newarr of arr){
           console.log(`${newarr} in ${ days++ } Days`)
        }
}

printForecase()

Answer 4

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();
