function foo() {}
var bar = foo <| function() {};
This is the first time I've seen something like this. What does <| mean?

Now that you have posted the link to the source, you can see in the comments at the top of the file exactly what it does (line 36):
ReplyDeletethe <| operator -- defines the [[Prototype]] of a literal...
For these examples <| used with a function expression sets the
[[Prototype]] of the object created as the value of the function's
"prototype" property to the value of the "prototype" property of the
the LHS object. This is in addition to setting the [[Prototype]] of
the function object itself. In other words, it builds sets the
[[Prototype]] of both the function and of function.prototype to
potentially different values.
That throws a syntax error for me ("unexpected token" on the "|")

It means syntax error - invalid JavaScript construct.
ReplyDeleteThere's no "<|". I think it's a mistake and there should be "||".
