Array.find()
Array.find() is used to return value of first element in the array that satisfies provided testing condition(user given condition).If the provided testing condition fails then array.find() returns undefined.In the following example array.find() checks whether the price elements in array are more than the given testing price(12000). If the provided testing condition true then first value that passed the test will be executed, if not undefined will be executed.
Example
<html>
<body>
<p id="price"></p>
<script>
var price = [3000, 21000, 28000, 20000, 15500];
function checkCost(cost) {
return cost >= 12000;
}
document.getElementById("price").innerHTML = price.find(checkCost);
</script>
</body>
</html>Output
