It's a better approach for some scenarios, because the Y axis is not actually a child of the X axis.

The Void Operator JavaScript introduces a new kind of operator that converts any value into an undefined one. It is symbolized "void".

It is used when you need for some expression to be executed but don't want the value to be used or displayed. In JavaScript arrays are indexed collections of data of any type what so ever. They can be indexed by a number or by a string: So Objects are also associative arrays as in awk.

It is possible, in a for loop, to make a variable visit every property in the object: As new properties were added to objects they were stored in an indexed array numbered [0], [1], In later JavaScripts Arrays have been separated from Objects and given a set of special functions and methods.

Each function call creates a new execution context global environment that includes an explicit local activation record called the "call object". The different execution objects are themselves properties of a global object and can be referred to TBA. When a function f is called with an object o like this o.

It replaces the symbolic this variable used in the function declaration. Functions can be used as-if they where data. For example an object can have a new property defined that is set to a function.

If, for example, an object o has function f assigned to property p: Functions can also be items in an array indexed by a number or a string.

Object, an object attached to a function that is shared by all objects that are created by the function which contains the default properties of the object. The prototype property allows a function to be used to create objects that share common methods and attributes.

Netscape 4 and above have two methods "apply " and later ones may add "call ". Scoping The scope for variables in a Function constructor is always the global scope. To find the meaning of a variable property in a function declaration or literal first check the local variables in the function, then the properties of the function's prototype object.

Then such in the function that declared the current function. Regular expressions however use dynamic scoping.The for loop execute and run the script till variable i is less than print the value of var i,followed by a break line, again the for loop execute and run the script after comparing variable i and variable j in the loop and print the output as per condition.

The do-while loop is a variant of the while loop, which evaluates the condition at the end of each loop iteration. With a do-while loop the block of code executed once, and then the condition is evaluated, if the condition is true, the statement is repeated as long as the specified condition evaluated to is true.

JavaScript For Loop Example This example will show you how to create a simple for loop that prints out the value of our counter until the counter reaches 5. Pay special close attention to the three different items that are on the first line of the for loop code.

Accessing the contents of an array. Each element in an array is given an index, which is an integer value between 0 and one less than the length of the first element has an index of 0, the second element has an index of 1, and so on.

It could be useful to use this approach to create an array of all the keys in an object and pass that back, or we could pass in a function to a method like this which iterates through the keys and values, and calls the function for specific values.

Javascript array forEach() method calls a function for each element in the array. This method is a JavaScript extension to the ECMA standard; as such it may not be present in other implementations of the standard. To make it work, you need to add following code at the top of your script.
