Template strings (or Template literals ) in Typescript are multi-line string literals that allow string interpolation. String interpolation allows us to include embedded expressions as part of the string. Template strings allows us to create multi-line strings, basic string formatting & tagged templat...

这与Perl、Python、Shell还有其他语言中的字符串插值(string interpolation)的特性非常相似。除此之外,你可以在通过模板字符串前添加一个tag来自定义模板字符串的解析过程,这可以用来防止注入攻击,或者用来建立基于字符串的高级数据抽象。 以下是例子: // String interpolation 字符串插值 使用 `xxx ${插值变量}`...
Improved Checking Against Template Strings with Interpolations TypeScript now more accurately checks whether or not strings are assignable to the placeholder slots of a template string type. Copy function a<T extends {id: string}>() { let x: `-${keyof T & string}`; // Used to error, no...
