title: how to get only numeric values avoiding qoutes numeric values?
body: <p>I have code that below:</p>
  
  <pre><code>if ((!isNaN(abc[i][j])) == [0-9]) {                         
      count[i][j] = abc[i][j];            
  } else {
      count[i][j] = "";   
  }       
  </code></pre>
  
  <p>Here abc is an array.

      [0-9] and entered 100 gives 100. Okay, now if I try to put "100" still gives me 100 output. I wanted only numeric values without any qoutes numberic values to accept. How to get it? Referred to W3schools, couldn't get idea how to avoid it. </p>
