String()

Converting to text

Goal

Learn how to convert values to text using String().

Explanation

  • String() converts any value to a text string.
  • Numbers, booleans, and other types can be represented as text.
  • After conversion, the value becomes a string.
  • String() is often used to build messages and display data to the user.
  • It is one of the most common ways to work with text in JavaScript.

Analogy

Imagine a label printer. It can print a text representation of any value.

Code

console.log(String(42));
console.log(String(true));

Result: "42" "true"

Common mistake

After String(42) you get text, not a number. Math operations will behave differently.

Remember

  • ✦ String() creates a string.
  • ✦ Any value can be shown as text.
  • ✦ The result is always a string.
