JavaScript: Find the longest word within a string

Sample Solution: -

HTML Code:

            <!DOCTYPE html> <html> <head> <meta charset=utf-viii /> <title>Detect the longest word within a string</championship> </head> <trunk>    </body> </html>

JavaScript Code:

            function find_longest_word(str) {   var array1 = str.friction match(/\west[a-z]{0,}/gi);   var outcome = array1[0];    for(var ten = 1 ; 10 < array1.length ; x++)   {     if(result.length < array1[x].length)     {     result = array1[x];     }    }   return result; } console.log(find_longest_word('Spider web Evolution Tutorial'));

Sample Output:

Development

Explanation:
Assume str = '@Web Evolution #Tutorial';

The match() method is used to retrieve the matches when matching a string confronting a regular expression.
Therefore str.match(/\w[a-z]{0,}/gi) will return ["Spider web", "Evolution", "Tutorial"].

For loop checks the length of the array element and compare with previous 1 and finally return the longest string.

The length property represents an unsigned, 32-bit integer that is always numerically greater than the highest alphabetize in the array.
Syntax -> arr.length

JavaScript: Tips of the Twenty-four hours

Returns the divergence between two arrays, after applying the provided function to each assortment chemical element of both

Example:

const tips_differenceBy = (x, y, fn) => {   const south = new Gear up(y.map(fn));   return 10.map(fn).filter(el => !south.has(el)); };  panel.log(tips_differenceBy([iii.1, 1.5], [iii.3, 3.8], Math.floor)); console.log(tips_differenceBy([{ ten: 3 }, { x: 2 }], [{ x: ii }], v => five.x));

Output:
