why not allow the name in the name/value pairs to be unquoted identifiers

Quote names with " is a lot simpler than “You may quote names with " or ' but you don’t have to, unless they contain certain characters (or combinations of characters that would make it a keyword) and ' or " may need to be quoted depending on what delimiter you selected.

Unquoted key name problem :

It turns out ECMA Script 3 has a whack reserved word policy. Reserved words must be quoted in the key position, which is really a nuisance. When I got around to formulizing this into a standard, I didn’t want to have to put all of the reserved words in the standard, because it would look really stupid.(

NOTE : These days you can even use reserve words without quotes, you only need quotes when you have some quotes or special character.

Git : Making the main branch identical to other branch

Problem : Some how your main branch got polluted (few bad commits) and you want to fix it ?

Solution : You can create a single commit that will make the current branch identical in contents (and implicitly in sync) with another branch.

Explanation : Roll back your branch to the commit you feel it was working fine and create/spun another branch off from there. Now cherry pick can be done for few good commits and new branch can be tested. Once that is fine, follow below commands which will eventually create a big merge commit to make your main (polluted branch) identical to fixed branch. The merge commit will remove all un-necessary files.

$ git reset --hard <another branch>
$ git reset --soft HEAD@{1}
$ git commit

Note : Please make sure that default rebase option is configured to false
command : git config –edit

The first (hard) reset grabs the contents of the other branch into your working directory. The second (soft) reset puts your commit pointer back at the tip of your original branch, but doesn’t change the files in your index at all, thus leaving them as they were in the other branch. You can then commit that state on top of your current branch’s latest commit.

How to Save google Maps locations using name you want

Bookmarking or saving locations to the app is handy but who searches for their friends’ place by address? Without the ability to rename the address to something more recognizable, you’d likely forget which address is where.

However, when you search for an address or locate current location and save it to the list, you won’t be able to rename the address through the app into something more recognizable. Let’s try to fix that.

We’re going to show you how to rename saved locations for the Google Maps app for both iOS and Android users.

Splice to add, replace and remove javascript array

Here is working code link : http://plnkr.co/edit/SHfpFQ?p=preview

Splice is an effective way to add, replace or remove elements from specific index in Javascript Array.

Javascript array splice() method changes the content of an array, adding new elements while removing old elements.

Syntax

Its syntax is as follows −

array.splice(index, howMany, [element1][, ..., elementN]);

Parameter Details

  • index − Index at which to start changing the array.
  • howMany − An integer indicating the number of old array elements to remove. IfhowMany is 0, no elements are removed.
  • element1, …, elementN − The elements to add to the array. If you don’t specify any elements, splice simply removes the elements from the array.

Return Value

Returns the extracted array based on the passed parameters.

If you specify a different number of elements to insert than the number you’re removing, the array will have a different length at the end of the call.

Examples

Using splice()

The following script illustrates the use of splice():

var myFish = ['angel', 'clown', 'mandarin', 'surgeon'];

// removes 0 elements from index 2, and inserts 'drum'
var removed = myFish.splice(2, 0, 'drum');
// myFish is ['angel', 'clown', 'drum', 'mandarin', 'surgeon']
// removed is [], no elements removed

// removes 1 element from index 3
removed = myFish.splice(3, 1);
// myFish is ['angel', 'clown', 'drum', 'surgeon']
// removed is ['mandarin']

// removes 1 element from index 2, and inserts 'trumpet'
removed = myFish.splice(2, 1, 'trumpet');
// myFish is ['angel', 'clown', 'trumpet', 'surgeon']
// removed is ['drum']

// removes 2 elements from index 0, and inserts 'parrot', 'anemone' and 'blue'
removed = myFish.splice(0, 2, 'parrot', 'anemone', 'blue');
// myFish is ['parrot', 'anemone', 'blue', 'trumpet', 'surgeon']
// removed is ['angel', 'clown']

// removes 2 elements from index 3
removed = myFish.splice(3, Number.MAX_VALUE);
// myFish is ['parrot', 'anemone', 'blue']
// removed is ['trumpet', 'surgeon']
