Basic JavaScript - Find the Length of a String

JavaScript
1

Tell us what’s happening:

I can’t make the lastNameLength be 8. I also don’t know how? I’ve watched the video over and over again but I still don’t understand it? could I please have some help on this question?

Your code so far

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

// Only change code below this line
let lastNameLength = lastName.length;
let lastName = "Lovelace";
console.log("Lovelace".length);

Hi there! Remove all of your code except this

3

To check the length, just use the dot notation with the variable you want to check. (In this case, the variable is lastName)

4

you can do that, you need to avoid syntax errors like declaring the same variable twice, which breaks everything

Let’s figure what mistake you have done:

  • The lastName variable is already declared in third line. So remove the second unnecessary declaration from the 7th line.
  • See, the lastNameLength is already declared at the top. But you have also declared below which is causing syntax error. So remove the keyword let from the second variable lastNameLength.
  • You have get the length of lastName variable and stored it in the variable lastNameLength, so you can console it direclty. Replace “Lovelace”.length with lastNameLength in the console statement.
