|  | 
 | |||
|  | ## Description
 | |||
|  | <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> ). </section> | |||
|  | 
 | |||
|  | ## Instructions
 | |||
|  | <section id="instructions"> Установите <code>someAdjective</code> и добавьте его в <code>myStr</code> используя оператор <code>+=</code> . </section> | |||

 | |||
|  | ## Tests

|  | <section id='tests'> | |||
|  | 
 | |||
|  | ```yml | |||
|  | tests: | |||
|  |   - text: <code>someAdjective</code> должен быть установлен в строку длиной не менее 3 символов | |||
|  |     testString: 'assert(typeof someAdjective !== "undefined" && someAdjective.length > 2, "<code>someAdjective</code> should be set to a string at least 3 characters long");' | |||
|  |   - text: Добавить <code>someAdjective</code> в <code>myStr</code> используя оператор <code>+=</code> | |||
|  |     testString: 'assert(code.match(/myStr\s*\+=\s*someAdjective\s*/).length > 0, "Append <code>someAdjective</code> to <code>myStr</code> using the <code>+=</code> operator");' | |||
