Description
join方法用于将数组的元素连接在一起以创建字符串。它需要一个用于分隔字符串中数组元素的分隔符的参数。这是一个例子： var arr = [“你好”，“世界”];
var str = arr.join（“”）;
//将str设置为“Hello World”
Instructions
sentensify函数内的join方法（以及其他方法）从字符串str的单词创建一个句子。该函数应返回一个字符串。例如，“我喜欢星球大战”将被转换为“我喜欢星球大战”。对于此挑战，请勿使用replace方法。 Tests
tests:
- text: 您的代码应使用<code>join</code>方法。
testString: 'assert(code.match(/\.join/g), "Your code should use the <code>join</code> method.");'
- text: 您的代码不应使用<code>replace</code>方法。
testString: 'assert(!code.match(/\.replace/g), "Your code should not use the <code>replace</code> method.");'
- text: <code>sentensify("May-the-force-be-with-you")</code>应该返回一个字符串。
testString: 'assert(typeof sentensify("May-the-force-be-with-you") === "string", "<code>sentensify("May-the-force-be-with-you")</code> should return a string.");'
- text: <code>sentensify("May-the-force-be-with-you")</code>应该返回<code>"May the force be with you"</code> 。
testString: 'assert(sentensify("May-the-force-be-with-you") === "May the force be with you", "<code>sentensify("May-the-force-be-with-you")</code> should return <code>"May the force be with you"</code>.");'
- text: <code>sentensify("The.force.is.strong.with.this.one")</code>应该返回<code>"The force is strong with this one"</code> 。
testString: 'assert(sentensify("The.force.is.strong.with.this.one") === "The force is strong with this one", "<code>sentensify("The.force.is.strong.with.this.one")</code> should return <code>"The force is strong with this one"</code>.");'
- text: '<code>sentensify("There,has,been,an,awakening")</code>应该回归<code>"There has been an awakening"</code> 。'
testString: 'assert(sentensify("There,has,been,an,awakening") === "There has been an awakening", "<code>sentensify("There,has,been,an,awakening")</code> should return <code>"There has been an awakening"</code>.");'
