But it turns out that this works in JavaScript indeed :D

Just check the code:

Boolean.prototype.ifTrue = function(p) { this.valueOf() && p() }

(1 < 2).ifTrue(() => console.log('hello')) // logs hello
(3 < 2).ifTrue(() => console.log('bye'))   // does nothing

I never thought that it could work :) But it does! Thanks!

And thanks for spreading the love for Smalltalk, I do really believe that it is one of the languages that more have contributed to the advance of the software engineering itself.

I wrote my own story like you showing the greatness of smalltalk (some from different points of view, all valid). And, if you don’t mind, I’ll link yours back.
