Build a message

Combine text with values and use common string methods.

Join text and values

The + operator can join strings. When one side is a string, the other value is converted to text. Use spaces inside your strings where needed.

const name = "Ada";
console.log("Hello, " + name + "!");

Output

Hello, Ada!

Clean up text

trim() removes whitespace from both ends of a string. toLowerCase() returns a lowercase version. String methods return new strings; they do not change the original.

const city = "  PARIS  ";
const cleaned = city.trim().toLowerCase();
console.log(cleaned);

Output

paris
