Both the power and simplicity of a program come from its abstractions. Any language that makes new abstraction easy allows for a seasoned professional to easily make simple and powerful programs. Beyond that, the language itself cannot do this work for you beyond providing libraries where other programmers have done it already, and shared their work. And the reason for this is simple. To make an abstraction, we must think, and no language can think for us. The power and simplicity of our code is a product of our thinking. The rest is just technical implementation based on specs. With languages that make abstraction hard, programmers have created tools to help. HTML and CSS have horrible abstraction features. Server-side Perl and PHP and client-side javascript has been used to abstract HTML. Sass, Less, and SCSS are tools invented for CSS. The learning curve for abstraction itself is language independent.
