Does JavaScript have a range() equivalent?

Is there a way to declare a range in Javascript/jQuery like we do in Python?

Something like this:

x = range(1,10)

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

Thanks.

Answer 1

By using some third party libraries like Underscore.js you can achieve the same behaviour as in Python http://underscorejs.org/#range

Answer 2

You simply can create an array, loop over the values using a for loop and pushing the values. There isn't anything built into the language.

Answer 3

Put this function in your Javascript code, and you should be able to call range() like you do in Python (but it only works for numbers):

function range(start, end)
{
 var array = new Array();
 for(var i = start; i < end; i++)
 {
 array.push(i);
 }
 return array;
}

• ted: Just interesting, how may [1..10] be implemented? =)
• David G: You mean for (var i = start; i < end; i++)
• thebjorn: Definitely useful, but not exactly like range in Python.. docs.python.org/library/functions.html#range :-)
