In sidekiq, what does the colon before variable mean?

I ran into a sidekiq configuration YAML file : 

---
:concurrency: 25
staging:
  :concurrency: 10
production:
  :concurrency: 25
:queues:
  - ["critical", 2]
  - high
  - low

and there are colons before variables. What do they mean?

If you load the above file in console, you're output will look something like this

For keys with colon prefixed

:concurrency: 25 will look like :concurrency => 25

For keys without colon prefixed

staging: will look like "staging"

Also, converting to symbol is very specific to Ruby only as the interpreter takes care of it.
