What is a template literal?
Template literals are literals delimited with backticks ( ` ), allowing embedded expressions called substitutions. Untagged template literals result in strings, which makes them useful for string interpolation (and multiline strings, since unescaped newlines are allowed).
What is a literal in JavaScript?
