On: Ways to Invoke a Function in JavaScript

[kmill]

I wasn't reading carefully, and I thought they mentioned it because it's slightly different from

    (function () { console.log("#"); })();

though not actually since the this is not being used.

I was expecting to see

    console.log.bind(console)("#")

as well.

Edit: bind is farther down in the comments.

bind is a way to create a function, not invoke one. Here you're invoking the function (that bind returned) in the normal way, using parenthesis.

The list seems to be about different ways a particular function could be called, rather than just the syntax of invocation. Imagine you are making a code analysis program and you want to find all the places console.log is called; I imagined the bind example as encompassing things like

    var log = console.log.bind(console);
    // ... ... ...
    log("#");

Ok: static analysis of a language where most fundamental relationships are resolved at runtime.

I guess this is one way to express the futility.

The lesson learned is hook console.log -- or whatever function you are interested in -- meaning, replace it with something that captures the context in which it is called and passes through the call to the original)
