with operator in JavaScript

Hello Friends,

I found one good thing in JavaScript, there is with operator in JavaScript, which you can say same as with operator in VB.NET. Its always helpful to define short name of big variable or replacement of such big variable; which lead us to make code more readable and maintain too.

In general when we are dealing with XML datasrouce in JavaScript; there always have long long variable name, of the value is so deep inside.


We have to write more lines of code to get all the details. Here we can use with, as we know part of path to reach final value is common which is xmlDoc.childNodes[1].childNodes[0], so we can put it into with keyword.

name = childNodes[1].childNodes[0].text;
add1 = childNodes[2].childNodes[0].text;
add2 = childNodes[3].childNodes[0].text;
email = childNodes[4].childNodes[0].text;
