From Ruby Variables To JavaScript Variables

I sometimes find myself writing so much Ruby that as soon as I am back in a JavaScript file, my code starts looking like this:

const my_javascript_var = 123;

It would be easy enough to hit caw to the delete the entire word and then retype it as camel case. I happen to have the Abolish.vim plugin installed, so there is an even quicker way.

If I hit crc over the variable, it will be coerced to camel case.

const myJavascriptVar = 123;

If I hit crs then it will be coerced back to snake case. Hit crc one more time and I can get back to writing some JavaScript.

See :h abolish-coercion for more details.
