<p>So I have a problem I'm trying to solve, but I need to iterate over two separate arrays of type []string. Is there a way to accomplish this in Go? Kinda something like this:</p>
<p><code>for nope, yep := range firstArray, secondArray {
fmt.Println(nope)
fmt.Println(yep)
}</code></p>
<p>Obviously that doesn't work, just trying to give you an idea of what I'm looking for.</p>
<p>EDIT:</p>
<p>Concatenating or comparing them isn't an option. I need to use the values in both arrays differently.</p>

Unfortunately that only works if both arrays are the same size, which won't always be the case. I updated your example to better describe my needs. <a href="https://play.golang.org/p/GNJ2tIRgnL" rel="nofollow">https://play.golang.org/p/GNJ2tIRgnL</a></p></pre>koalainthetree: <pre><p>Can you take the length of the longest one and iterate over both of them that way?</p></pre>muffinz0: <pre><p>Actually, I just figured it out! <a href="https://play.golang.org/p/1Arw3M_KIn" rel="nofollow">https://play.golang.org/p/1Arw3M_KIn</a></p></pre>fubo: <pre><p>These are pretty different cases.</p>
<p>If you have arrays [1, 2, 3] and [4, 5], <em>parallel iteration</em> will yield two or three iterations:</p>
<ul>
<li>x=1, y=4</li>
<li>x=2, y=5</li>
<li>... followed by either skipping x=3 because there isn't a corresponding y value, or having an error, or assigning y to 0, or something else depending on how you code it.</li>
</ul>
<p>Whereas <em>nested iteration</em> (one for loop inside another) will yield six iterations:</p>
<ul>
<li>x=1, y=4</li>
<li>x=1, y=5</li>
<li>x=2, y=4</li>
<li>x=2, y=5</li>
<li>x=3, y=4</li>
<li>x=3, y=5</li>
</ul>
<p>If you want to generate all possible pairings of elements from each array (a Cartesian product), you want nested iteration. If you want to step through <em>both</em> arrays <em>in step</em> with each other, pairing the elements from one array with <em>corresponding</em> elements of the other, you want parallel iteration.</p></pre>djherbis: <pre><p><a href="https://play.golang.org/p/eASwJNh1xb">https://play.golang.org/p/eASwJNh1xb</a></p></pre>muffinz0: <pre><p>Thank you for your help!</p></pre>Fwippy: <pre><p>You just need to use two normal loops, one inside the other.</p>
