In Template’s onCreated, onRendered, helpers, events, what is this and this.data stand for?

And
what is the difference between this and Template.instance() ?
what is the difference between this.data and Template.currentData() ?

And it seems no matter in where Template.instance().data always equals to Template.currentData() ?

I’m totally confused.

this refers to the current context, try use a differnet function inside a template and voila this inside the function has different “meaning” so either you store it inside a variable or use Template.instance() to get the context inside the function.

Template.instance().data === Template.currentData() cause currentData() is just a short hand for Template.instance().data.

keep in mind Template.currentData() is reactive
