ERB (Embedded Ruby in HTML)

ERB

ERB allows us to embed Ruby directly into HTML. The ERB library can process a special syntax that mixes Ruby into HTML and produces a final 100% HTML string.

It works in conjunction, here, with separate view template files ending in .erb.

To use ERB:

require 'erb'
