Example
You can try to run the following code to learn about the MAX and MIN value in JavaScript −
<html>
<head>
<script>
function showMinValue() {
var val = Number.MIN_VALUE;
alert("Value of Number.MIN_VALUE : " + val );
}
function showMaxValue() {
var val = Number.MAX_VALUE;
alert("Value of Number.MAX_VALUE : " + val );
}
</script>
</head>
<body>
<p>Click the following to see the result:</p>
<form>
<input type="button" value="MIN" onclick="showMinValue();" />
<input type="button" value="MAX" onclick="showMaxValue();" />
</form>
</body>
</html>
