Convert a 2D JavaScript array to a 1D array
<p>I want to convert a 2D JavaScript array to a 1D array, so that each element of the 2D array will be concatenated into a single 1D array.</p>

<p>Here, I'm trying to convert <code>arrToConvert</code> to a 1D array.</p>

<pre><code>var arrToConvert = [[0,0,1],[2,3,3],[4,4,5]];

console.log(get1DArray(arrToConvert)); //print the converted array

function get1DArray(2dArr){
    //concatenate each element of the input into a 1D array, and return the output
    //what would be the best way to implement this function?
}
</code></pre>
