Extracting every other value from an array can be achieved by iterating through the

Hi, I'm looking to create a function that will log every other value from an array. For example, if we have:

var myArray = [1,45,65,98,321,8578,'orange','onion'];

I want the console.log output to be 45, 98, 8578, onion... Does anyone have any suggestions on how to achieve this?

Answer №1

If you want to eliminate certain items based on their index, you can utilize the Array#filter method.

The new array will only contain items with a truthy division remainder when divided by 2.

var exampleArray = [1,45,65,98,321,8578,'orange','onion'];

console.log(
  exampleArray.filter((item, index) => index % 2)
)

To showcase every alternate item in an array (starting from position 1), I would implement a loop:

const displayEveryOtherItem = function(array) {
  for (let i = 1; i <= array.length - 1; i += 2) {
    console.log(array[i]);
  }
}

displayEveryOtherItem([2, 56, "apple", 78, 3245, 8719, "banana", "carrot"]);
