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
My code seems to be correct, but it won’t let me pass to the next step (I prefer not to use the solution button).
Here’s a screenshot:
Be sure to check for typos/misspellings.
So sorry! I didn’t notice that I misspelt “length”.
It works now. Thank you @mtf.
Hello, what would the .length for numbers be, I tried assigning a variable to a number and then putting the variable in the console.log but it returns undefined, thanks fairly new to this.
Numbers are exact values that don’t have a length. Sure they have numeral characters, etc., but as objects they have no length. Further to this, numbers are not iterable.
Can somebody please explain this concept in simpler terms? Thank you very much
a = 42
Above we assign an integer value (a number) to the variable,
a. When we poll the type of
a we are actually polling the type of
a is not an object, but a reference to an object.
42 is identified by the interpreter as being a
number type so gives it a wrapper object of that type.
typeof 42 => 'number' typeof a => 'number'
a refers to an instance of a number type.
I think I understand it better now, thank you for your explanation sir.
