title: JS: Boolean Array vs Int8Array
body: <p>What would be smaller in memory size between:</p>
  
  <p><code>[true,true,true,true,true,true,true,true,true,true]</code></p>
  
  <p>and</p>
  
  <p><code>new Int8Array(1,1,1,1,1,1,1,1,1,1)</code> ?</p>
  
  <p>Considering regular arrays can contain anything, each slot must have a size of 32 bits while the Int8Array would be 8 bit each. Is that right?</p>
