My 2014 JavaOne

It has been fifteen years since I last attended JavaOne in San Francisco and I am quite excited. I spent 26 hours in an aeroplane to get to San francisco, I certainly have forgotten how torturous that is. Since fifteen years ago, Java has grown tremendously and the schedule shows it, there are 537 sessions with 572 speakers. Putting my schedule together was excruciatingly difficult, choosing what to miss out on. But with the help of many coin tosses I got to the following schedule:

JavaScript: Splicing an Array

This JavaScript blog series will be posted more regularly in 2014. To kick off, lets look at how to dynamically add and remove items anywhere in an array. Arrays in JavaScript have a splice function to do just that.

It has the following syntax

array.splice(index, quantity, item1, ..., itemX)   returning an array

where the parameters are defined as:

index  :  it is required and specifies the position at which to add or remove items. If it is negative it will calculate from the end of the array.

quantity : it is optional and specifies the number of items to be removed from the index onwards. To not remove any items, set it to 0. If it is not specified it will remove all elements after the index.

itemX : it is optional and is the items to be added to the array at the specified index.

Lets define an array

var myArray = [1,2,3,4,5]

Now lets remove all elements from index 4 onwards

myArray.splice(4)

This results in the following array

[ 1, 2, 3, 4 ]

Now let us add some elements to our array starting at index 4,

myArray.splice(4,0,5,6,7,8,9,10)

This results in the following array

[ 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 ]

Now lets replace elements with values 4 and 5 with 11 and 12

myArray.splice(3,2,11,12)     //remove 2 elements at index 3 and add 11 and 12 at index 3

This results in the following array

[ 1, 2, 3, 11, 12, 6, 7, 8, 9, 10 ]

Now lets remove elements with values 11 and 12 from the back of the array

myArray.splice(-7,2)

This results in the following array

[ 1, 2, 3, 6, 7, 8, 9, 10 ]

Pretty cool hey, that's enough on splicing, its time for you to experiment with it. Till next time enjoy!!!

2013; break; 2014;

Year 2013 delivered Edward Snowden to the world, who single handedly confirmed that we live in an Orwellian world. All technology corporations, both hardware and software corporations cannot be trusted protecting simple basic human rights. More terrifyingly, most people could not be bothered and choose willingly to live in the matrix. 

Year 2014 will be spent focused on looking for ways to protect my right to privacy. I have also resolved to blog at least once a week.

Happy New Year, may 2014 bring you safer technology and the restoration of basic freedoms......
