I loved Delphi 15 years ago. It was WISWIG, click on a button, write an event handler, drag and drop components, it even generated some boilerplate code for me. That was bliss. I learned how to do event driven UI's back then. Today I use jQuery much the same way, but without the nice RAD. Is there a Delphi-esque RAD for JavaScript?
I work in a similar place. IMS and COBOL is all over the place.
Delphi is too. I maintain mostly C code written 20 years ago.
It pays better than any job I've had previously with up to date technology stacks.
A bunch of mates are Coldfusion coders. Now they are in demand because all these odd places have legacy CF code they have to deal with.
In 10 years time all over the place will be piles of Angular, Node & whatnot to maintain.
The pile just keeps getting bigger.
