Iterating over object with "name in in object" it's super awesome 👍. I ve never seen this before

[jsomhorst]

great content. But what I miss in this is a 8th tip. Let de API do the hard work. Filtering and such is best done (when having lots of data) to a server. It can utilize caching and such.

Whole v-for just in few clicks:
I perfer assign key to index, when I am surtan that list length not gonna change.
For that purpose I have shortcut even in Webstorm: f + tab ==> v-for="($item$, index) in $data$" :key="index"
(this f + tab shorthand configured to work ONLY in vue template and ONLY in the tags)
$data$ and $item$ - just places to navigate with tab after snippet was unwrapped.

There is one point that creator missed.
In vue3.x V-IF has Higher precedence as compared to V-FOR

I want to know how to do a range loop in reverse order. For example, from 10 to 1.

You must learn regexp one time and don't use useless libraries
