How would you define 'Idiomatic' in the context of Idiomatic Javascript?

Question

During his initial discussion on TypeScript, Anders repeatedly mentions the term 'idiomatic javascript'.

Can you clarify the specific definition of idiomatic in this context?

I've attempted to research this on Wikipedia and Stack Overflow, but I'm still struggling to grasp its full meaning in this particular situation.

Answer №1

When we talk about idiomatic in this context, we're referring to the way JavaScript is typically written and understood by those who work with it.

In simpler terms, it's about what feels natural to someone who is fluent in the language.

For instance, a common practice in idiomatic JavaScript is to return an object like so:

function foo(){
    return {x:3,y:5};
}
var point = foo();

On the other hand, using "out parameters" is often seen as less idiomatic:

function foo(out){
    out.point = {x:3,y:5}
}
var out = {};
foo(out);
point = out.point;

Closures are another example of idiomatic JavaScript that are commonly used.
