Great article!
It's worth noting that the first 2 examples can be written ever so slightly shorter using Array.from as the Array.from method supports a mapping function as it's second argument.
Array.from
Here's the first example using Array.from:
Array.from({ length: 1000 }, Math.random)
And the second example:
Array.from({ length: 1000 }, (v, i) => i)
You're right! This way is slightly shorter! I'll replace mine with them Thank you mate!
Here is what I use
[...Array(1000).keys()]
Array from for the win I had an issue with array fill hahaha
