Pls help me troubleshoot this code. I want to write the JavaScript equivalent of a Python function

The function takes a sentence as argument and returns the longest word. JavaScript (pls check the JS tab for my code): https://code.sololearn.com/WcbNVaVkabwW/?ref=app This is how it should work (Python): https://code.sololearn.com/clz157k6uDhM/?ref=app

Maybe your JS interpreter doesn't support the '...' operator of the parameter of the rest ^^ You can rather normally use the .apply() method of Function prototype: Math.max.apply(null,list) ... should works ;) (but be sure you doesn't ommit a closing parenthesis or such syntax/typo error :P)

/* Your first mistake is to use your 'i' index iterator as the item of the list... access to the item is done by: arrayName[index] Second mistake is in use of Math.max() method: arguments are not allowed to be directly passed as an array... but fortunaly, you can pass an array as an argument list, with the operator 'parameter of the rest': Math.max(...arrayName): Third non blocking mistake: the unnecessary use of the 'break' statement... */ // fixed code: function longest(string) { var list = []; var splitString = string.split(" "); for(var i = 0; i < splitString.length; i++) { list.push(splitString[i].length); } for (var i = 0; i < splitString.length; i++) { if (splitString[i].length == Math.max(...list)) { return splitString[i]; // break // unnecessary, return is a form of radical break ^^ } } } alert(longest("This is the longest sentence I've never seen..."));

Thanks. A lot. Math.max.apply(null, list) worked.

Thanks @visph. I've corrected the errors. However, now I'm getting a syntax error (error message references the line containing Math.max). I ran the code using both ScriptIt and AIDE Web on a tablet.
