I recently got introduced to a JavaScript library called Handlebars. Is templating used a lot in professional web development? I’ve seen it on a few job postings, and I’ll having to admit that it does make creating different versions of the same element easier.
yes, templating is used a lot in professional web development. 
Is Handlebars one of the main frameworks? What are some of the others? Which one do you use a lot?
Yes, Handlebars is quite popular. Some others are Mustache, Jade and Slim.
The ones I’m most familiar with are ERB and Haml which are used in Ruby.
