Update index.html (destructuring) (#1536)

index.html line 67~70 (Kor version)
original example 
<pre class="brush: js">var foo = ["one", "two", "three"];

var [one, two three] = foo;

this example is not intuitive,  it looks same.
but in English example, there are some differences in example.

for other newbies like me, fix this plz!!
