[javascript] assigning function to variable in PXCE SOLVED

[Mathew]

I'm probably missing something, but if I assign a built-in function to a variable, and try to run that variable, nothing happens and the script is aborted with no error. If I put it in a try catch block, it never gets to the catch, either.

Code: Select all

{
const a = console.println;
a("test");
// script will be aborted above with no output to the console.
}

Hi Mathew,
When you assign an object member function to a variable, the function loses its binding to that object. println can only work as a member of console object.

Perhaps you want something like this:

Code: Select all

{
const println = console.println.bind(console);
println("test");
}

Ahh thank you. Makes total sense. Thanks for taking the time.
