bd7123c9c448eddfaeb5bdef	Find the Length of a String	1	https://scrimba.com/c/cvmqEAd	18182

--description--

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

"Alan Peter".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.

--instructions--

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

--hints--

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

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

// Only change code below this line

lastNameLength = lastName;

--solutions--

var lastNameLength = 0;
var lastName = "Lovelace";
lastNameLength = lastName.length;
