JavaScript template engine handlebars usage examples and techniques

When we were developing the DOM operation, it was no problem with a simple JS application, but what if you needed to manipulate a lot of chunks in my document every time you updated the view? At this time the JS template came in handy.

This is an example where we can embed the JSON data in the template as we think it is.

<! 
  DOCTYPE html>  
See this example, we feel very happy it ~ is so. We can get the data from the back end and throw it to the front end without having to write the various "<>" separation symbols.
 
To traverse the data inside, print out
 
<script id= "Each-template" type= "Text/x-handlebars-template" >
  {{#each people}}
    ... output person ' s info here ...
  {{/each}}}
</script>
 
Data rendering if data is available
 
<script id= "Each-template" type= "Text/x-handlebars-template" >
  {{#if people}}
    ... output person ' s info
  here ... {{/if}}}
</script>
