javascript

date object

var today = new date(); // return todays date

to make out own obj

we can we

var day= new Date(2011,0,1);// year month and day , month as an exception starts as 0

var daytime= new Date(2011,0,1,0,0,0);//also adds hours , mins and secs with previous

Get methods of date obj

day.getMonth();
day.getYear();
day.getTime();

Set methods

day.setMonth(5);

comparison

var date1= new Date(2001,1,1);
var date2= new Date(2001,1,1);

if(date1==date2)//false

if(date1.getTime()==date2.getTime())

CREATING NEW OBJECT

var player= new object();

now its data members will be declared as

player.name="fred";
player.age=13;
player.rank=1;

A variable inside a object is called its properties, same as data member

shorthand to create an object

var player= {name: "Fred",age:13,rank:1};

git bash

but shows only of unstaged files

git diff --cached
after we add a file to the stage area and we want to see the differences then we need to use --cached otherwise the changes wont show

shortcuts
if the log becomes to big , to come out of it we need to press ctrl+z+z or ctrl+c(checked)
