How do you escape braces {{var}} in a polymer template?

Question

How do you escape curly braces in a Polymer template? I've seen both of these as suggestions but they both throw "Invalid expression syntax" errors.

1. {{ '{{' }}var{{ '}}' }}
2. {{ '{{var}}' }}

Answer 1

How about {{'\{{var}\}'}}? Seems to work.

Answer 2

To escape things like {{..asdf..}} or [[..asdf..]] in regular HTML code in the template use ­ in between: {­{..whatever..}­}
