< section id = 'description' >
Так же, как мы можем построить строку из нескольких строк из строковых < dfn > литералов< / dfn > , мы также можем добавить переменные в строку, используя оператор equals ( < code > +=< / code > ).

## Tests
< section id = 'tests' >
```yml
tests:
2019-08-28 16:26:13 +03:00
- text: < code > someAdjective</ code > should be set to a string at least 3 characters long
testString: assert(typeof someAdjective !== 'undefined' & & someAdjective.length > 2);
- text: Append < code > someAdjective</ code > to < code > myStr</ code > using the < code > +=</ code > operator
testString: assert(code.match(/myStr\s*\+=\s*someAdjective\s*/).length > 0);
