Template literals (also known as template strings) are a powerful feature in JavaScript that allows for more flexible and readable string creation. They are defined using backticks (`) instead of single or double quotes, offering several key advantages:
- Multi-line strings: Template literals can span multiple lines without the need for concatenation or special characters.
- String interpolation: Embed expressions directly within the string using
${expression}
syntax. - Tagged templates: Use a function to parse and manipulate the template literal, enabling custom string processing.
Use Cases:
- Dynamic HTML generation: Easily create HTML elements with dynamic content.
- Parameterized queries: Construct database queries with variable values.
- Custom string formatting: Implement specialized formatting rules for different data types.
- Internationalization (i18n): Manage translations and localized text within your application.
