The major difference between Mustache templates and Underscore.js templates is that Mustache does not allow for the placement of arbitrary JavaScript within an alternate form of its tags; it only allows for expressions.
In its simplest form, a Mustache template maps values from a JavaScript object directly to their respective template expressions, represented by the keys for those object values. Take an object such as the one shown here, for example:
