 The syntax for template strings is similar to [string literals](#string-literals): They are also delimited by double quotes, the text can contain escape sequences, and raw newlines can be inserted. The additional syntax are _template expressions_, which are any expression enclosed by `#!sds {{` and `#!sds }}`. There must be no space between the curly braces.
 
-These template expressions are evaluated, converted to a string and inserted into the template string at their position. The template string in the example above is, hence, equivalent to the [string literal](#string-literals) "1 + 2 = 3".
