Javascript Prototype General Enquries and Assign Id by Array Index

this one helps. I personally never use the new keyword if I can avoid it and do pure prototype-based programming with Object.create. Here's a simple example. I create a prototype-object called rectangle and then create an object called myRectangle which inherits from rectangle.
code :
var rectangle = {
  init: function( x, y, width, height ) {
    this.x = x;
    this.y = y;
    this.width = width;
    this.height = height;
  move: function( x, y ) {
    this.x += x;
    this.y += y;

var myRectangle = Object.create( rectangle );
myRectangle.init( 0, 0, 2, 4 );
myRectangle.move( 3, 5 );
function Rectangle( x, y, width, height ) {
  this.x = x;
  this.y = y;
  this.width = width;
  this.height = height;

Rectangle.prototype.move = function( x, y ) {
  this.x +=x;
  this.y +=y;

var myRectangle = new Rectangle( 0, 0, 2, 4 );
myRectangle.move( 3, 5 );
function Parent() {
  /* expensive and possibly side-effect inducing initialization */

Parent.prototype.parentMethod = function() {};

function Child() {}

Child.prototype = new Parent();
Child.prototype = Object.create( Parent.prototype );
var parent = {
  parentMethod: function() {}

// Using underscore for stylistic reasons
var child = _.extend( Object.create( parent ), {
  childMethod: function() {}

var instance = Object.create( child );

How do I insert an array at an array specific index without removing existing data at specified index using angular

hop of those help? I have a array, in that array I want to add another array on a particular index if the condition is met. , First off, I see various problems with your code.
code :
$rootScope.rows=[{...}, {...}];
cellValues=["some", "value"];

$rootScope.rows.splice(j, 0, cellValues);

console.log($rootScope.rows) //[{...}, {...}, ["some", "value"]]
rowValues=$rootScope.rows.slice(0,j).concat(cellValues, rowValues);
[["some", "value"], {...}, {...}]
var rows=[1,2,3];

var cellValues=[4,5,6];

var newRow=rows.concat(cellValues);

console.log(newRow); //[1,2,3,4,5,6]
var obj1={

var obj2={

var obj3=angular.extend(obj1, obj2);

//nested arrays
var rows=[

//index of the nested array to merge
var arrayIndex=1;

//new array to merge with nested array (rows[arrayIndex])
var valuesToAdd=[22,33,44];

//Reference the nested array and merge it with the new array.

console.log(rows[arrayIndex]); //[5, 6, 7, 8, 22, 33, 44]
for (var j = 0; j < $rootScope.input_columns.length; j++) {
for (var j = 0; j < $rootScope.input_columns.length; j++) {
    for(var i=0;i<cellValues.length; i++) {

will help you if you do not want to initialize the whole array, you can use memset or a similar function.
code :
#include <string.h>

memset(&buf[8], 0, 4);
#include <algorithm>
