title: Bold only a part of string in javascript
body: <p>Im displaying a message on a webpage in this format "5 pencils will be given to 6 students".</p>
  
  <pre><code>"span style="" data-bind="text: app.summary()"/span" 
  </code></pre>
  
  <p>Knock out databind is used here. <code>summary()</code> is a js method which returns me this message in the format defined in <code>message.js</code> file as <code>"{0} pencils will be given to {1} students"</code>
  but i need to display only the numbers as bold in the final HTML page.</p>
  
  <p>I.e.<strong>5</strong> pencils will be given to <strong>6</strong> students.
  I don't want to create individual span and split the string message.</p>
  
  <p>Is there any way to do that?</p>
  
  <p>Thanks</p>
