PHP<\/p>\n

1) Difference between interface and abstract class. Write code to show example of each. Can a class derive from abstract class and implement an interface as well? (Yes)<\/p>\n

2) Write a function to test a palindrome.<\/p>\n

Javascript :
\n1) What is the difference between
\nx = 1;
\nvar x = 1;
\nwindow.x = 1;<\/p>\n

2) Write a function to add an array of numbers using the arguments variable<\/p>\n

var data = [1,2,3,4];\r\nconsole.log(sum(data));\r\n\r\nfunction sum() {\r\n   var myData = arguments[0];\r\n   return myData.reduce(function (acc, num) { acc += num; return acc});\r\n}\r\n<\/pre>\n
3) write a function to implement mult(4)(5)<\/p>\n
function mult(x) {\r\n   return function(y) {\r\n       return x*y;\r\n   }\r\n}\r\n\r\nvar ans = mult(4)(5);\r\n<\/pre>\n
Still concise :<\/p>\n
function mult(num1) {\r\n  return num2 => num1 * num2;\r\n}\r\n\r\nconsole.log(mult(4)(5));<\/pre>\n
4) Write a function to output alert(1), alert(2) every 1 second till 5 times
\nSimilar to question asked in Ten-X interview.<\/p>\n
5) write a function to put spaces in a string “Hello World” ==> “H e l l o W o r l d”.<\/p>\n
var spacify = function (str) {\r\n    return str.split('').join(' ');\r\n};\r\n\r\nconsole.log(spacify(\"Hello\"));\r\n<\/pre>\n
Is it possible to write a function spacify like “hello world”.spacify()<\/p>\n
String.prototype.spacify = String.prototype.spacify || function() {\r\n  return this.split('').join(' ');\r\n};\r\n\r\nconsole.log(\"Hello\".spacify());\r\n<\/pre>\n","protected":false},"excerpt":{"rendered":"
