'string text line 1' = 기존
'string text line 2' = 기존
`string text line ${one}` = 템플릿 리터럴
`string text line ${two}` = 템플릿 리터럴
**위와 같이 템플릿 리터럴은 작은 따옴표나 큰 따옴표 대신 백틱(`)으로 감싸준다**
// Untagged, these create strings:
`string text`
`string text line 1
string text line 2`
`string text ${expression} string text

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.
