Nested Quotes

When quotes are nested within each other, it’s a common practice to alternate between single and double quotes. This helps avoid the need for escaping quotes and makes the code more readable.

// Using single quotes inside double quotes:
let message1 = "He said, 'Hello!'";

// Using double quotes inside single quotes:
let message2 = 'She exclaimed, "Wow!"';
