JS.BASE.TEMPLATE.CURLY.SPACING
Require or disallow spacing around embedded expressions of template strings
We can embed expressions in template strings with using a pair of ${ and }.
This rule can force usage of spacing within the curly brace pair according to style guides.
Copy
let hello = `hello, ${people.name}!`;
