Generate random number,random alphunumeric and random alphabets based on dynamic length passed as argument.

var randomUpperAlphabet = (length) => {	
    var chars = 'ABCDEFGHIJKLMNOPQRSTUVWXYZ';
    var result = '';
    for (var i = length; i > 0; --i) result += chars[Math.floor(Math.random() * chars.length)];
    return result;
};

var randomLowerAlphabet = (length) => {	
    var chars = 'abcdefghijklmnopqrstuvwxyz';
    var result = '';
    for (var i = length; i > 0; --i) result += chars[Math.floor(Math.random() * chars.length)];
    return result;
};

var randomString = (length) => {	
    var chars = 'ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz';
    var result = '';
    for (var i = length; i > 0; --i) result += chars[Math.floor(Math.random() * chars.length)];
    return result;
};

var randomNumber = (length) => {	
    var chars = '1234567890';
    var result = '';
    for (var i = length; i > 0; --i) result += chars[Math.floor(Math.random() * chars.length)];
