Handlebars, as described by its official website, provides the power to let you build semantic templates effectively with no hustle and bustle. Handlebars is also compatible with Mustache templates. You can also replace Mustache with Handlebars and continue using your current templates.
I shall talk about Mustache next, as it also one of the best template engines. You can download and install Handlebars by going to the following link: https://handlebarsjs.com . The entire installation guide is given step-by-step there.
Mustache loves to call itself “logic-less” template engine because there are no cumbersome and confusing conditional if and then statements or looping constructs embedded within a Mustache template. Looping and conditionals can be done using processing lists, section tags, and lambdas. Mustache has all about tags. Few tags are replaced with a value, few with nothing, and others with a list or series of values.
