Yes, string interpolation is possible in TypeScript, and it is also known as template literals or template strings. It allows you to embed expressions within string literals, using backticks (`) instead of single or double quotes. To include a variable or expression within the string, use the ${expression} syntax. This feature makes it easier to create more readable and concise strings without resorting to string concatenation.
Here's an example of string interpolation in TypeScript:

In this example, the message variable uses a template literal to construct a complete string with interpolated variables firstName, lastName, and age. The output will be:
Hello, my name is John Doe and I'm 30 years old.
