Alternatively, if you need to find out more about the data context of a specific template fragment, you can also write a dedicated {{log}} helper:

Template.profile.helpers({
  log: function () {
    console.log(this);
  }
});
And use it directly in your templates:

<template name="profile">
  {{#with profile}}
    {{log}}
    <img src="{{avatar}}"/>
    <p>{{name}}</p>
  {{/with}}
</template>
