Front End Web Development Techdegree Graduate 19,854 PointsWhat does Chalkley mean when he says that the anonymous function is "more expressive"?
Chalkley mentions that writing a callback function inline and anonymously makes it more expressive. Here's the function he's referencing in the video:
executeCallback(function () {
console.log('Hello');
});

17,094 PointsAnother way that I personally understand it is that maybe he is saying that anonymous functions are more "explicit". It is direct, clear, whereas if you utilize a named function, unless you look at the code directly, it is easier to mistake as potentially being a variable. But, with an inline, anonymous function, you cannot make that mistake since it is explicit (and not implied via a "name") aka "more expressive".
