Hey there, it depends on a lot of things. Out of interest, what programming languages do you already know, and why do you want to learn a new one. It sounds like perhaps you are experienced in a language with fewer jobs and want to maximize your chance to get a job? In any case JS/Typescript or Python are safe choices. If you want to learn more data-science/AI stuff then Python would be a good choice. For front-end or full-stack web (as in front-end and back-end) JS would be a good choice. Another choice is Go - if you think you are likely to go into a devops type role and want to understand Kubernetes, Docker, Terraform, etc. more closely. Other decent choices for finding work are C# and Java.
