The ECMAScript standard (edition 2) defined the catch keyword and reserves it for future use. Edition 3 mandates that this should now be supported in a compliant interpreter.

In anticipation of that, it is available in JavaScript version 1.4. This is also now supported in JScript version 5.0 as well.

Refer to the try ... catch ... finally topic for more details.
