filer array but value code example

Example 1: filter

function isBigEnough(value) {
  return value >= 10
}

let filtered = [12, 5, 8, 130, 44].filter(isBigEnough)
// filtered is [12, 130, 44]

Example 2: javascript array filter

run.addEventListener("click", function () {
    let array = [];
    people.forEach((elem) => {
      // elem before age to target
      if (elem.age > 18) {
        array.push(elem); // each array elem > 18 is "pushed" inside the new array
        // console.log(array); nope : messes things up
      } else {
        (""); // no need to declare this through console.log
      }
    });
    console.log(array); //and there you have it : filtered array
  });
