title: How to use a variable value as placeholder in Vue with typescript
body: <p><code>&lt;input type="text" placeholder="{{fromTimeWindow}}" v-model="fromTimeWindow"/&gt;</code></p>
  
  <p>or<code>&lt;input type="text" v-bind:placeholder="{{fromTimeWindow}}" v-model="fromTimeWindow"/&gt;</code></p>
  
  <p>both of the above above code gives me error. I want to use variable "fromTimeWindow" value as placeholder.</p>
