It's just a notation for where a variable value should be substituted.

They could have picked anything, but double brackets are both reasonably concise yet very unlikely to be found in HTML code otherwise.

why not using literal template by sing bracket instead of double brackets? would't that be more concise?

You could use any notation you like. This example was probably chosen to be more distinct from the placeholders in template strings.

In this case, it's not "handlebars" but some custom code that uses similar tokens.
