I have an xjs/ssjs script that, when called once works as expected, but whenãcalled a second time I get:ããTypeError: redeclaration of constããIf I wait a few minutes and run the script again it works as expected thenãcraps out.

It can take a few minutes for the client's session to expire and a new context to be created. So basically you may end up reusing the same global scope across multiple executions of a script.ããSo using 'const' at the *top level* of an XJS/SSJS script is inadvisable. Use 'var' instead.ããIt's okay to use 'const' inside of functions.ããIt's probably also okay to wrap your entire script in an IIFE so that you get a fresh scope for each request. However, this context reuse was done for performance reasons, so you'd be sacrificing any performance gain by doing that.ãã(function () {ã // This is an IIFEã // It's an Immediately Invoked Function Expressionã})();ãã---ãechickenãelectronic chicken bbs - bbs.electronicchicken.comã þ Synchronet þ electronic chicken bbs - bbs.electronicchicken.comã
