function findLongestWordLength(str) {
let arr = str.split(' ');
let lengths = arr.map(word => word.length);
console.log(Math.max(lengths));
}
findLongestWordLength("The quick brown fox jumped over the lazy dog");
console.log(Math.max(lengths)) results in NaN, console.log(Math.Max(...lengths)) works. Why does lengths need to be spreaded? Math.Max takes an array as its argument, & lengths is an array? Thanks
Math.Max takes an array as its argument
This is not the case according to MDN:
The Math.max() function returns the largest of the zero or more numbers given as input parameters, or NaN if any parameter isn't a number and can't be converted into one.
