How get the first three letters of a string in JQuery or Java?

Question

I have this code

  <span class="sp_1">{$s.username}</span>
{/foreach}

Information given is not precise, you have added java tag instead of javascript. Little more specific would help. — neotam, Jan 05 '20 at 13:01

you just have to use substring(startingFromIndex, endingIndex)

{foreach from=$last_user item=s}
    <span class="sp_1">{$s.username.substring(0, 3)}</span>
{/foreach}
