JavaScript Template Literals
Template literals introduced in ECMAScript 6 (ES6) provide a way to embed words and multiline strings in JavaScript. They provide a simpler and more readable syntax than traditional concatenation methods.
Syntax-
Template literals are enclosed by backticks (`) rather than single quotes
(' ') or double quotes (" ").
let greeting = `Hello, world!`;
and 
Features of Template Literals
Embedded Expressions
You can add JavaScript expressions to template literals using the ${} syntax.
Expressions in ${} are evaluated, converted to strings, and inserted into template literals.
let name = 'Alice';
console.log(`Hello, ${name}!`); // Output: "Hello, Alice!"
Multiline Strings
Template literals can span multiple lines without the need for

and other escape characters.
let multiline = `This is
a multiline
string`;
console.log(multiline);
// Output:
	 "This is
	 a multiline
	 string"
Expression Interpolation
Template literals allow you to add variables and expressions directly to a string, making it easier to create strings with dynamic content.
let a = 10;
let b = 5;
console.log(`The sum of ${a} and ${b} is: ${a + b}.`);
// Output: "The sum of 10 and 5 is: 15."
and 
Tagged Templates
Advanced functions use "tagged templates", where a function (tag) can process the template itself and its input before outputting the final string.
function myTag(strings, ...values) {
 console.log(strings); // Array of string literals
 console.log(values); // Array of interpolated values
 return 'Processed string'; // Processed result
}
let a = 10;
let b = 5;
let processed = myTag`The sum of ${a} and ${b} is ${a + b}.`;
console.log(processed); // Output: "Processed string"
and 
Benefits of template literals
Readability- The readability of complex strings is improved by allowing variables and expressions to be entered directly.
Maintenance- Easy to maintain compared to traditional wiring methods.
Multiline Support- Simplifies multiple line wiring without complicated joins or nine line lines.
and 
Compatibility
Template literals are supported in both modern browsers and versions of Node.js that support ES6 and later.
