Yeah, considering that `Function.prototype.apply === console.log.apply` there are a lot of dupes here. I would consider eval/new Function to be a legitimate fourth way though.
Eval is another way to run arbitrary JS code. It's cheating here because nothing about the use of eval is specific to calling a function.
According to that standard, opening an external interpreter would be yet another way.
Agree with the above that there are really only three ways here.
Yes, you have a good point about eval and anything else that boils down to invoking a string as a function.
As other people have pointed out in the gist, the syntax for tagged template literals gives an additional way to invoke a function
foo`abc ${bar} ${baz}`
[["abc ", " ", ""], bar, baz]
There are additional ways specific functions are called -- I'm thinking of toString and valueOf.
