no-template-curly-in-string

禁止在常规字符串中使用模板字面占位符语法

ECMAScript 6 允许程序员通过在两个反引号 () 之间编写诸如 ${variable}之类的表达式，使用模板字面量而不是字符串连接来创建包含变量或表达式的字符串。当想使用模板字面时，很容易使用错误的引号，通过编写"${variable}"，并以字面值 “${variable}”` 而不是包含注入表达式值的字符串结束。

¥ECMAScript 6 allows programmers to create strings containing variable or expressions using template literals, instead of string concatenation, by writing expressions like ${variable} between two backtick quotes (). It can be easy to use the wrong quotes when wanting to use template literals, by writing “${variable}”, and end up with the literal value “${variable}”` instead of a string containing the value of the injected expressions.

¥This rule aims to warn when a regular string contains what looks like a template literal placeholder. It will warn when it finds a string containing the template literal placeholder (${something}) that uses either " or ' for the quotes.
