JavaScript Foundations - Methods Code Challenge

Hey guys

So I'm currently doing the JavaScript Foundations - Methods code challenge. I get to part 4 and I'm coming across some problems. The question states

"Update the variable of 'wordBrown' on about line 21, to extract the substring of "brown" from the string 'quick'."

I have been declaring the following

var wordBrown = quick.subStr(9, 5);

And I get the following error:

You're missing the .substr() method. I am quite confused about the question and the error message that I am getting.

In the interim I will have a play around with the console and if I get the problem solved on my own I will let you all know.

Any advice would be greatly appreciated!

Thanks

Stu :)

Hello Stuart, the substr method is all lowercase. Also, remember that, in JavaScript, strings (and other kinds of objects) are zero-based, and spaces are considered characters too.

"The quick brown fox jumps over the lazy dog" has the 'b' at the 10th position starting at 0.

var wordBrown = quick.substr(10, 5);

I get the position 10 but not understanding position 5

var wordBrown = quick.substr(10, 5);

Hey Victor,

I literally figured this out a few seconds after you posted this up!

I knew that it would be a silly error.

Thanks for that

Stu :)
