I’m stuck on Intro to JavaScript, Lesson 1 Exxercise 7. I do not get an error message, but I can’t advance. What do I do?

Is this instruction you are stuck on?

Use the .length property to log the number of characters in the following string to the console:

'Teaching the world how to code'

I used .length, but I think it is the program. I have reset the exercise several times, reread the text and carefully followed the instructions and used the hint. The program will not let me move forward. What should I do?

This means,

console.log( ... );


console.log("Teaching the world how to code".length);

I created another account and was able to move forward. I’m not sure what the problem was. Thanks

I had the same problem. It was my fault, I wrote lenght instead of length.

I am having the same issue. I don’t want to create a new account as I have other lessons I am working on. I know the language fairly well as I have created websites before and used Node.js and React so I know that what I am doing is the correct syntax but it’s not taking it. How do I go about forcing the lesson to pass me?

Hi, i have done what the exercise has asked me to and passed it… But why is it relevant?.. like why would i want to know how many letters are in the sentence?

Seems like a reasonable question. I’ll try to give a reasonable answer. You might be hosting a message board, and have a character limit per post. This forum, for example has a minimum characters per post limit. As you get further along in learning to code, you’ll come to realize that you use the .length property of different objects quite often.

Hello , one basic question :
.log is a method
.length is a properties

So properties = method ?
else what the difference between ?

A method is an attribute, but that does not make an attribute a method. A method is function, so performs some task. .length is a value, only.

We poll values, and call (or invoke) methods.

hi in this chapter the characters are supposed to be 25 or 30 ?

console.log("Teaching the world how to code".length);

Is that the line you are measuring?

It’s 30 characters because .length counts each space as a character.

m = "23.556"
d = m.substring(m.indexOf('.') + 1).length
