Ring 一 Acquired by Amazon for $1.2B

Nest 一 Acquired by Google for $3.2B

If you missed out on these spectacular early investments in the Smart Home space, here’s your chance to grab hold of the next one.

They have generated over 20X growth in share price for early shareholders, with significant upside remaining as they just launched in over 100 Best Buy stores.

2024: Another incredible year of brand new JS feature upgrades with ES15.

From sophisticated async features to syntactic array sugar and modern regex, JavaScript coding is now easier and faster than ever:

1. Native array group-by is here

2. Resolve promise from outside -- modern way

With Promise.withResolvers().

It's very common to externally resolve promises and before we had to do it with a Deferred class:

structuredClone(): The easiest way to deep copy objects in JavaScript

Deep copying is a regular programming task for passing or storing data.

We always had to lean on third-party libraries for deep copying and keeping circular references.

All that changes now with the new structuredClone() — an easy and efficient way to deep copy any object.

Cloning circular references with ease:
