Here are the steps to installing and setting up GDB on Mac OS Sierra/High Sierra. Run brew install gdb. On starting gdb, you will get the following error:

Unable to find Mach task port for process-id 2133: (os/kern) failure (0x5).
 (please check gdb is codesigned - see taskgated(8))

To fix this error, follow the following steps:

const avengers = ['Thor', 'The Hulk', 'Captain America'];
let guardians = ['Star Lord', 'Gamorra', 'Drax', 'Rocket', 'Groot'];
// Spread out arrays in a new array and put a new value in between them
const heroes = [...avengers, 'Loki', ...guardians];

// Adding new stuff to an array just got easier too
guardians = [...guardians, 'Mantis', 'Yondu', 'Nebula'];

// Or simply making a TRUE copy of an array
const avengersCopy = [...avengers];

The future is here: Classless object-oriented programming in JavaScript.

Douglas Crockford, author of JavaScript: The Good parts, recently gave a talk called The Better Parts, where he demonstrates how he creates objects in JavaScript nowadays. He doesn't call his approach anything, but I will refer to it as Crockford Classless.

Crockford Classless is completely free of class, new, this, prototype and even Crockfords own invention Object.create.

I think it's really, really sleek, and this is what it looks like:
