JavaScript - Array find() example (returns the value) - Qomplainerz - 04-04-2023

The HTML part between the <body></body> tags looks like this:

Code:
<p>Click "Test" to return the value of the first element in the array that has a value above this number:</p>
<p><input type="number" id="ageToCheck" value="18"></p>
<button onclick="myFunction()">Test</button>
<p id="demo"></p>


The JavaScript part looks like this:

Code:
const ages = [4, 12, 16, 20];

function checkAge(age)
{
  return age > document.getElementById("ageToCheck").value;
}

function myFunction()
{
  document.getElementById("demo").innerHTML = ages.find(checkAge);
}
