--description--

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

console.log("Alan Peter".length);

The value 10 would be displayed in the console. Note that the space character between "Alan" and "Peter" is also counted.

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

--instructions--

Use the .length property to set lastNameLength to the number of characters in lastName.

--hints--

You should not change the variable declarations in the // Setup section.

assert(
  code.match(/let lastNameLength = 0;/) &&
    code.match(/const lastName = "Lovelace";/)
);

lastNameLength should be equal to eight.

assert(typeof lastNameLength !== 'undefined' && lastNameLength === 8);

You should be getting the length of lastName by using .length like this: lastName.length.

assert(code.match(/=\s*lastName\.length/g) && !code.match(/lastName\s*=\s*8/));

--seed--

--seed-contents--

// Setup
let lastNameLength = 0;
const lastName = "Lovelace";

// Only change code below this line
lastNameLength = lastName;

--solutions--

let lastNameLength = 0;
const lastName = "Lovelace";
lastNameLength = lastName.length;
