This feature is stage 4 and will be included in the 2018 edition of ECMA-262. Summary: ES6 template literals forbid certain escape sequences, like `\u{not hex}`. But tagged templates expose to user code the raw code points of the template literal, and some applications only care about those. As such, this stage 4 TC39 proposal allows such invalid escape sequences in tagged template literals. The "cooked" value of such a template (that is to say, with escape sequences interpreted), which is also exposed to user code, is `undefined`. Interop risk: This new language feature allows syntax that was previously a SyntaxError, so compatibility risk is low. Firefox has shipped this feature ( https://bugzilla.mozilla.org/show_bug.cgi?id=1317375 ). Safari has implemented this feature ( https://bugs.webkit.org/show_bug.cgi?id=166871 ) and shipped it in at least Tech Preview. Edge has not implemented this feature ( https://github.com/Microsoft/ChakraCore/issues/2344 ).
