JavaScript: Find the Length of a String

You can find the length of a String value by writing .length after the string variable or string literal.

Example:

"Peter Max".length;    // 10

For example, if we created a variable var firstName = "Charles", we could find out how long the string "Charles" is by using the firstName.length property.

Exercices

Use the .length property to count the number of characters in the lastName variable and assign it to lastNameLength.

// Example
var firstNameLength = 0;
var firstName = "Julia";
firstNameLength = firstName.length;

// Setup
var lastNameLength = 0;
var lastName = "Steven";

// Only change code below this line
lastNameLength?;
/* Your test output will go here.
