title: Confusion about return keyword in programming with JS example
body: <p>I am new to programming and was learning JS. The keyword I encountered is the <code>return</code> keyword. Let's look at this example:</p>
  
  <pre><code>let number = (num1, num2) =&gt; {
    return num1 + num2;
  }
  
  let result = number(5,6);
  </code></pre>
  
  <p>The question is, is it true that we use the <code>return</code> keyword in programming to reuse the value that we want to return from a function, so, basically, the <code>return</code> keyword is useful when we want to achieve the "reuse"? </p>
