56533eb9ac21ba0edf2244ed	Appending Variables to Strings	1		将变量附加到字符串

Description

正如我们可以在字符串文字中构建多行的字符串一样，我们也可以使用加号等于（ += ）运算符将变量附加到字符串。

Instructions

设置someAdjective并使用+=运算符将其附加到myStr 。

Tests

tests:
  - text: <code>someAdjective</code>应设置为至少3个字符长的字符串
    testString: 'assert(typeof someAdjective !== "undefined" && someAdjective.length > 2, "<code>someAdjective</code> should be set to a string at least 3 characters long");'
  - text: 使用<code>+=</code>运算符将<code>someAdjective</code>附加到<code>myStr</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");'

Challenge Seed

// Example
var anAdjective = "awesome!";
var ourStr = "freeCodeCamp is ";
ourStr += anAdjective;

// Only change code below this line

var someAdjective;
var myStr = "Learning to code is ";

After Test

console.info('after the test');
