Note that the original proposals for this type of rule use the verbage "no-useless-interpolation".

See

• Rule proposal: detect useless template literal interpolation #2846,
• Add no-useless-interpolation eslint/eslint#10798

no-useless-interpolation

...oh, I think that's a much better name for this rule. D'oh. I wish I'd thought to request the name change back in #7957.

IMO we should rename the rule. Which isn't a process we have documented yet. Filed #8548.

I don't really like no-useless-interpolation, FWIW. no-useless-template-expression is better, if you want. interpolation is not a uniformly recognized word and has so many meanings—in mathematics it means something entirely different.

It has been [0] days since a unified TypeScript glossary would have been useful

Is there something relative not-overloaded we can call the interpolated insides of a template literal? The TemplateLiteral AST node calls it expressions... but that term is used in a lot of places. 😕

On MDN, we call it "embedded expression" or just "expression". In the ES spec, it's called "substitution" (in many places). I think both are better than either interpolation or template-literal.

FWIW, the very first sentence on the MDN page uses the term "interpolation" https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Template_literals, so I'm skeptical that it's not a widely recognized term.

That said, I do very much agree no-useless-interpolation doesn't quite make me happy without the word "template" in it.

Might no-useless-template-substitution be inoffensive to everyone, with a mention in the doc page that says 'also referred to as "string interpolation"'? That way there's no confusion what we're referring to, and people will find it with whatever search time they use.

"Interpolation" is the effect or purpose of template literals, but the code entity itself we call it an "embedded expression".

no-useless-interpolation-expression

Hmm. Accurate and precise, but "interpolation" isn't a term many devs associate with template literals... I think I'm leaning towards no-useless-template-expression as @Josh-Cena suggested in #8544 (comment). 🤔

Hello! Just checking whether this issue has enough common ground to be actionable with a rename to no-useless-template-expression and doc updates?

Thanks for the ping - I'd say let's go with no-useless-template-expression for now. If someone realizes they have a strong preference later, it shouldn't be too difficult to suggest -> apply changes in the PR.
