JavaScript Template Literal
- Template literals (Template strings) - JavaScript | MDN
Template literals are literals delimited with backtick (`) characters, allowing for multi-line strings, for string interpolation with embedded expressions, and for special constructs called tagged templates.
# Syntax
// Untagged, these create strings:
`string text`
`string text line 1
string text line 2`
`string text ${expression} string text`
// Tagged, this calls the function "tagFunction" with the template as the
// first argument and substitution values as subsequent arguments:
tagFunction`string text ${expression} string text`
