String Interpolation #
String interpolation allow us to easily concat variable and some strings easily.
You can surely write and js code without string interpolation but it will make you life simpler.
- The code become easily to understand.
- No need to use unwanted + for string concatenation.

to concat with some string.
Let me show you how world will look like without string interpolation and how it will make a significant difference.
let num = 21;
let result = "Square of " + num + " is " + num * num + ".";
print(result);
Let’s now use the string interpolation and see how it is better choice for us as a programmer.
let num = 21;
let result = `Square of ${num} is ${num * num}`;
print(result);
