Here is a solution you can implement:
let numbers = [5, 10, 15, 20, 25];
let counter = 0;
let result = numbers.reduce((accumulator, currentValue) => {
if(counter === 0) {
accumulator.push(currentValue);
counter++;
} else {
accumulator[accumulator.length-1] += currentValue;
counter = 0;
}
return accumulator;
}, []);
console.log(result);.as-console-wrapper {min-height: 100%!important; top: 0}Here's another method to achieve that:
const values = [10, 20, 30, 40, 50];
const oddNumbers = values.filter((value, index) => index%2 - 1);
const evenNumbers = values.filter((value, index) => index%2);
const finalResult = oddNumbers.map((val, idx) => val + (evenNumbers[idx] || 0));
