javascript increment

[krishvasu]

Explain the pre increment and post increment?
what is the difference between the post increment and pre increment?

[chathura86]

this is common to the all programming languages (or at least most), not only for JS.

pre increment (++i) means the nutriment will be done before the execution of the expression,

post (i++) means increment will be done after the executing the expression;

	var i = 10;
	document.write(i);
	document.write(i++);	//post incriment -> this will print 10 and the increment the i by 1 so the i = 11
	document.write(++i);	//pre incriment -> this will print 12 because i was 11 and it will be creased by 1 before printing it
