Have you ever wanted a quick and easy way to combine arrays in ColdFusion.  I have done this a number of ways in the best, but came across this gem and thought I would share.

All ColdFusion arrays are of the Java vector type, we can use the underlying java.util.Vector class methods, specifically the addAll() method.

Keep in mind that this is not a "documented" use of arrays in ColdFusion, so at any version it may stop working.

Merging two arrays in ColdFusion with the java.util.vector.addAll()

ar1 = ["a","b","c"]; ar2 = ["d","e","f"]; ar1.addAll(ar2); writeDump(ar1);

Thanks for the coding nugget. That pretty slick.

Your Development Team Is at Capacity. Here’s How to Keep Critical Work Moving!

The problem is not that your team lacks priorities.It is that maintenance, delivery, and long-term improvement are competing for the same people.

For companies running business-critical CFML, ColdFusion, or BoxLang applications, that pressure can be especially difficult to solve. Experienced developers are not always easy to hire quickly, application knowledge may be concentrated in one or two people, and a generalist may need significant context before taking ownership of the work. A permanent hire can also require a significant investment in recruiting, compensation, onboarding, and long-term capacity even when the immediate need is a specific project, urgent maintenance, or a period of transition.

Copy of BoxLang AI 3.4 Blog Series Part 5 : Reasoning Without the Guesswork

Reasoning-capable models have been usable in BoxLang AI for a while. params passes straight through to the provider body, so params: { thinking: { type: "enabled", budget_tokens: 10000 } } for Claude, or params: { reasoning_effort: "high" } for OpenAI, already reached the API. What never worked was reading the reasoning back. It was parsed out on arrival and silently dropped. In 3.4.0, that's fixed, and it's fixed the same way for every provider.
