title: 2 binary strings. The function will multiply these two arguments and return the result as a binary string
body: <blockquote>
    <p>And Write a JS function that takes 2 arguments: 2 binary strings. The
    function will multiply these 
           two arguments and return the result as a binary string.</p>
  
  <pre><code>    Note_: A binary string is a sequence of bytes, such as `"1001001100"`
     input= ("01011001010101", "11011111010101"),
       output= 100110111101101011110111001
  </code></pre>
  </blockquote>
  
  <pre><code>For Example :   
  str1 = `"10"`  
  str2 = `"100"`  
  Output = `"1000"`
