I have a array:
let numbers = [5, 10, 15, 25, 30];
I want to increment them all by one using a for loop. The result should be 6, 11, 16, 26 and 31.
But I can do this:
let numbers = [5, 10, 15, 25, 30];
for (let i = 0; i < numbers.length; i++)
console.log(numbers + 1);
let numbers = [5, 10, 15, 25, 30];
for (let i = 0; i < numbers.length; i++) {
numbers[i]++
}
Use this loop:
for (let i = 0; i < numbers.length; i++){
numbers[i] += 1
}
console.log(numbers)
Output: [6, 11, 16, 26, 31]
const numbers = [5, 10, 15, 25, 30];
const result = numbers.map(num => num + 1);
console.log(result); //[6, 11, 16, 26, 31]
