# Basic Algorithm Scripting - Find the Longest Word in a String

Tell us what’s happening:
I found this solution more explanatory till i got maxLength = words[i].length; My question is that how did maxLength discovered the longest word in the sentence and was able to return the value of 6 which is truely the length of the longest word “jumped”? If you remove the .length, i.e maxLength = words[i], and u log maxLength to the console, the console will return “The” which is a 3 letter word. I hope i am able to convey my message clearly.

``````function findLongestWordLength(str) {
let words = str.split(' ');
let maxLength = 0;

for (let i = 0; i < words.length; i++) {
if (words[i].length > maxLength) {
maxLength = words[i].length;
}
}

return maxLength;
}

console.log(findLongestWordLength("The quick brown fox jumped over the lazy dog"));
``````

Challenge: Basic Algorithm Scripting - Find the Longest Word in a String

You are getting the length of the string from `words[i].length`, e.g. 3 or 4 or 5 or 6.
Then you are comparing which is bigger and store it into maxLength variable.

Try console them out:

console.log(maxLength, words[i], words[i].length)

Thanks, but this doesn’t answer my question sir/ma. Pls I need more replies. my question is that I want to know how maxLenght or words[i].length got to know which of the words from the sentence has the longest length.

I would skip trying to decipher this answer. The answer itself isn’t really useful. The practice coming up with a solution is more important.

I think this solution has syntax that you don’t understand. I’d try to write your own with syntax you are more comfortable with.
