A function that retrieves an array containing elements that exceed a specified number and a given array

Is there a way to create a function that takes an array and a number as parameters, then returns a new array with only the elements from the original array that are greater than the given number?

For example:

[10, 25, 16, -5, 30, 15, 24] , 16

The output should be:

[24, 25, 30]

Answer №1

If you're looking to filter elements from an array based on a certain condition, the filter method is your best bet. This handy function creates a new array containing only elements that meet the criteria defined by a given function.

function filterNumbers(arr, target) {

  return arr.filter((item) => {
    return item > target;
  });
}

console.log(filterNumbers([10, 25, 16, -5, 30, 15, 24], 16));
