javascript - What is the correct term for separation of scripting languages? -

i have developed webbased shop-system in single page approach , using model view controller design pattern.

i have few php files application layer, html templates , javascript file presentation layer. html files being rendered on client data provided server json file.

there no case of mixing scripting languages. not have html tags hardcoded in application or presentation layer , vice versa, no mixed php/javascript. not onclick attribute.

i can remember professor huge fan of this, seperate scripting languages, , agree. hate reviewing , fixing code see mixed php, html, js , css code.

is there specific term 'clean scripting' approach?
