Catching errors in JScript .NET is done via three statements: try, catch, and finally. Here is the skeleton of a code block that catches exceptions:

  try {
     [tryStatements]
  } catch(exception) {
     [catchStatements]
  } finally {
     [finallyStatements]}
Where:
tryStatements are statements where an error can occur. Optional.
    • exception is any variable name. The initial value of exception is the value of the thrown error. Required.
    • catchStatements are statements to handle errors occurring in the above tryStatements. Optional.
    • finallyStatements are statements that are unconditionally executed after all other error processing has occurred. Optional.
