apt-get/yum/pkg install firefox?
And most people install firefox/chrome on windows rather than use IE.
Installing Tk/Tcl is easier than installing firefox/IE/chrome. Tk/Tcl does not require a lib to handle inconsistencies between different browsers and different versions of the same browsers (ff).
Btw :
Tcl/Tk = 29Mb
Firefox = 40Mb
Chrome = 52Mb
Memory footprint: Tcl/Tk is low usable in embedded system // most browsers have memory leaks.
Tcl/Tk // browsers:
- Positioning elements: Tk/Tcl 3 geometry managers (grid, packing...) while W3C CSS box model is an inconsitent mess
- Canvas: native // can or cannot be there (old versions) requires js
- Vectorial: Native // SVG
- Async : observers on variable (bind) & is aync by nature // callback in js
- Numbers : string coercion is sane // String coercion is inconsistent float by default (crypto does not like float)
- Functional : who cares? btw lists are lists not object
- Scopes : sane vs insane
- Modularity : Supports C binding AND module // $.getScript(url, callback)
- IO: accessing local files is possible // is not
- Widgets: you can make your own & reuse them by design
Tcl/Tk is way easier to learn than angular.
Why angular pop suddenly? Because angular bloated code aims at doing what tcl Tk does natively: makes UI components communicate together... without burning both CPU & RAM
So ... given the level of wtf in web development, tcl/tk seems pretty a smart choice nowadays ... if you care more about coding functionalities that works in a small footprint with less bugs than eye candying.
Edit: Bonus my C+tcl/tk code from 1996 with nice graphs still compile and work in 2016 ... 20 years stability.
