JavascriptWeb DevelopmentObject Oriented Programming

Template were introduced in ES6 to allow embed expressions inside a string. Instead of ‘’ or “” quotation marks they use the backticks (``). They offer a much better way of string interpolation and expressions can be embedded in a way like ${a+b}. It offers a much nicer syntax than the + operator.
