What Template Literals Actually Do in JavaScript
- Template literals in JavaScript allow for string construction using backticks, which treat the string as a single structure with dynamic parts.
- Expressions inside ${} are treated as full JavaScript code and can include function calls, math operations, ternary checks, or property access.
- Template literals simplify string building, making code cleaner and easier to read compared to traditional concatenation methods.
- Tagged templates in JavaScript allow for custom string processing by handing control to a function during construction.
- Tagged templates break strings into sections, evaluate expressions, and pass parts to a function for custom formatting.
- Tag functions receive plain string sections and evaluated expressions as input and can shape the result in various ways.
- Tagged templates offer structured handling of dynamic content, making tasks like HTML escaping easier and more organized.
- Tagged templates are commonly used in CSS-in-JS libraries, query builders, markdown formatters, and translation functions.
- Regular template literals immediately build the string, while tagged templates delay final string construction until the tag function decides.
- Tagged templates provide greater control over string processing, allowing for logic injection, escaping, and custom formatting.
