Range in Javascript/jQuery? [duplicate]

Question

Possible Duplicate:
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.

For fun try: function r(start,end){ start = start || 1; return end >= start ? r(start,end-1).concat(end) : []; } — KooiInc

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

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.

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;
}

Just interesting, how may [1..10] be implemented? =)

You mean for (var i = start; i < end; i++)

Definitely useful, but not exactly like range in Python.. docs.python.org/library/functions.html#range :-)
