JavaScript EvalError Object

There are several types of errors that we encounter in JavaScript, for example, SyntaxError, RangeError, ReferenceError, EvalError, etc. The EvalError indicates an error regarding the global eval() function. 

Newer versions of JavaScript however do not throw EvalError.

Syntax:

new EvalError()
new EvalError(message)

Parameters: The message is an optional parameter that provides details about the exception that occurred.

Return value: A newly constructed EvalError object.

Below are some examples of JavaScript EvalError.

Example 1:

Javascript

<script>
  try {
    throw new EvalError('EvalError has occurred');
  } catch (e) {
    console.log(e instanceof EvalError);
    console.log(e.message);
    console.log(e.name);
  }
</script>

Output:

true
EvalError has occurred
EvalError

Example 2:

Javascript

var score={
  checkerror:function (score){
    if(score<0)
    {
       try{
         throw new EvalError('Error occurred');
       }catch(e)
       {
          console.log(e.message);
       }

    }
  }
}
console.log(score.checkerror(-3));

Output:

Error occurred
undefined
