Question
What is the error in the following JavaScript code which is enclosed by script tags : <script>let num = 1;try { num.toPrecision(500);}catch(err) { document.getElementById("demo").innerHTML = err.name;}</script>A. Syntax ErrorB. Eval ErrorC. Type ErrorD. Range Error
Solution
The error in the given JavaScript code is D. Range Error.
