Template literals are literals delimited with backtick ( ` ) characters, allowing for multi-line strings, string interpolation with embedded expressions, and special constructs called tagged templates. Template literals are sometimes informally called **template strings**, because they are used most commonly for string interpolation (to create strings by doing substitution of placeholders). However, a tagged template literal may not result in a string; it can be used with a custom tag function to perform whatever operations you want on the different parts of the template literal.
