even low end smartphones work ok with basic javascript. the people who live on $2 a day mostly have a feature phone that is barely internet capable (remember WAP?) or they have no phone at all. i don't know about modern feature phones, but i expect they can handle javascript just fine, because it doesn't make sense to build a new phone today that doesn't. (i just did a search on some african online sites and found that smartphones can be had from $30, but most importantly that new web capable feature phones are not any cheaper (should those even be called feature phones?)) where internet is available it is usually not that slow either because it doesn't make sense to build a slow internet. i mean, it may be slow compared to what we are used to but even 1Mbps is enough to load at least text oriented websites, even with javascript. those companies do need to offer a service quality that people are willing to pay for. slow internet is a problem of old infrastructure, but developing countries tend not to have old infrastructure to begin with.
