If I have an HTML5 component/WebComponent that has a component.html file that defines a <template>, does it make sense to have a <!DOCTYPE html> declaration in component.html? That is, which of the following is best practice?
<template>
<!-- some html content -->
</template>
Or
<!DOCTYPE html>
<template>
<!-- some html content -->
</template>
Both will be parsed and processed the same way in all modern browsers that support the
templateelement.One is a few octets lighter!
So it depends if you prefer speed over strict standards compliance
Following the KISS principle: The less code I write (and read), the better I feel ;-)
