String Interpolation in JavaScript

String interpolation refers to construction of dynamic strings by embedding expressions or variables directly within a string literal.

These are the following ways to interpolate the given strings:

1. Template Literals (ES6)

Template literals are the most modern and preferred method for string interpolation in JavaScript. They use backticks (`` ` ``) and ${} syntax to embed expressions.

Hello, Alice!

2. String Concatenation (Before ES6)

Before ES6, string interpolation was achieved using the + operator to concatenate strings and variables.

Hello, Alice!

3. Using String.concat() Method

The String.concat() method can also be used for string concatenation, though it's less commonly used for interpolation.

Hello, Alice!

4. Array Join() Method

You can use an array and the join() method to interpolate strings, though this is less common and more verbose.

Hello, Alice!

5. Using a Custom Function

A custom function can be used to handle string interpolation, especially if the string structure is complex or repeated.

Hello, Alice!

6. Tagged Template Literals

Tagged template literals allow you to parse template literals with a function.
