How can I check on the value of a template variable? If I'm used to PHP's var_dump() and print_r() to check the value of a variable, how can I evolve to inspect things in Craft where Twig's dump isn't available?
If you have devMode set to "true" in your config files, you can use "dump" in a twig template like this without any plug in needed:

{{ dump(myArray) }}
