ES6 getter/method without curly braces

Question

I have some classes which consist of many short getters/methods.

Example:

get jQuery() {
  return this.pageConfig.jQuery || jQuery;
}

An arrow function with similar content may be written as follows:

() => this.pageConfig.jQuery || jQuery;

Which is a one-liner and thus consumes only 1/3 of vertical space.

But it is not a getter nor a method.

Is there a recommended way of writing getters/methods in the form of a one-liner? (if possible without curly braces and without the return keyword)

My getters and methods need not modify the object. They are just reading.

Answer 1

For a one liner, just go with this:

get jQuery() {return this.pageConfig.jQuery || jQuery;}

Arrow functions are not for method definitions because they use the lexical this, whereas a method wants the object this. Remember that while arrow functions are a nice shorthand, they also affect the value of this in a way that is not usually compatible with method definitions.
