The some() method of JavaScript is used to check if any of the elements in an array fulfills the condition.
The syntax is as follows −
array.some(function(currentVal, index, arr), val)
Above, the parameters under function(), include currentVal – value of the current element, index – array index, whereas val the array object the current element fits
Let us now implement the some() method in JavaScript −
Example
<!DOCTYPE html>
<html>
<body>
<h2>Ranking Points</h2>
<p>Is any point above 400...</p>
<button onclick="display()">Result</button>
<p id="demo"></p>
<script>
var pointsArr = [50, 100, 200, 300, 400, 500, 600];
function pointsFunc(points) {
return points > 400;
}
function display() {
document.getElementById("demo").innerHTML = pointsArr.some(pointsFunc);
}
</script>
</body></html>Output
Click the “Result” button −
Example
<!DOCTYPE html>
<html>
<body>
<h2>Ranking Points</h2>
<p>Is any point equal to 550...</p>
<button onclick="display()">Result</button>
<p id="demo"></p>
<script>
var pointsArr = [10, 20, 30, 40, 50, 60, 70, 80, 90, 1000];
function pointsFunc(points) {
return points == 550;
}
function display() {
document.getElementById("demo").innerHTML = pointsArr.some(pointsFunc);
}
</script>
</body></html>Output
Click the “Result” button −
