saranshkon CSS: Has a Parent Selector Now

saranshkon Flatten Arrays in Vanilla JavaScript with Flat() and FlatMap()

agreed, though I doubt there's anything we can do about it.

saranshkon Flatten Arrays in Vanilla JavaScript with Flat() and FlatMap()

you are right, I was trying to format it for HN but somehow screwed up copy pasting, though it'd be ["system-admin", "developer", "basic"] and not ['basic', 'system-admin', 'developer']

saranshkon Flatten Arrays in Vanilla JavaScript with Flat() and FlatMap()

there have been a lot of those added to the ES spec lately and a lot more coming soon. So it is always good to check MDN because I usually end up learning something new mostly.

saranshkon Flatten Arrays in Vanilla JavaScript with Flat() and FlatMap()

added this to the post as well, a place where there is an array inside an array of objects and you want all those. For example, if we want to extract all roles from the array:

[ { name: "Saransh Kataria" , roles: ['system-admin', 'developer'] }, { name: "Wisdom Geek" , roles: ['basic'] }, ].flatMap(x => x.roles);

// Output => ["admin", "system-admin", "developer"]

saranshkon Using GroupBy on an array of objects in JavaScript

while there is nothing wrong with that, it's always good to have these things built-in as native functions instead.

saranshkon Using GroupBy on an array of objects in JavaScript

probably would not have been written then, it is a stage 3 proposal but should be merged in hopefully soon.

saranshkon Using GroupBy on an array of objects in JavaScript

all of lodash features would probably become a native thing soon enough

saranshkon Using GroupBy on an array of objects in JavaScript

groupByToMap would be useful in that case as pointed out in another comment. Updated the post with that.

saranshkon Ask HN: Do Y Combinator startups hire outside US

I don't think there is a generic answer to this. It mostly depends on the startup size, their legal team and the team's. I have seen quite a few hire outside US, and then there obviously are startups outside the US that YC funds too.

saranshkon Load balancing and its different types

vanilla JS might be too much to maintain. I have already started working on the Gatsby version and will try and accelerate that.

saranshkon Load balancing and its different types

Ha, I know. It's a single VM instance right now. I have been thinking of migrating to Gatsby for quite some time now. This unexpected traffic and the server limitations give me a reason to get working on it!

saranshkon Load balancing and its different types

Concepts are definitely transferrable across domains. And then adapted according to desired outputs. Cost of performance is interesting and somewhat similar to the least-time approach but adapted to the supercomputers domain.

saranshkon Load balancing and its different types

We all learn everyday. I am learning from the comments here as well. The best we can do is accept we were wrong and correct it.

saranshkon Load balancing and its different types

Added least time to the post as well. Thank you!

saranshkon Load balancing and its different types

Thank you. I am not sure how to introduce transit and the concept of hops in an introductory post without explaining in depth about the networking side of it. Maybe you could help me out with that?

saranshkon Load balancing and its different types

I know about the caching issue is a little trivial but it was worth mentioning. Though I should have mentioned the low TTL piece. I will add that to the post. And also will add the health check part too. Reading up a bit about it. Thanks for the information!

saranshkon Overcoming Procrastination and the Akrasia Effect

Haha, you can treat yourself on becoming a multi-tasking procrastinator for putting off a bunch of shit at the same time!

saranshkon Overcoming Procrastination and the Akrasia Effect

Thanks for the support.

saranshkon Overcoming Procrastination and the Akrasia Effect

Sorry about that. Apparently someone was DDOSing as soon as this started getting some traffic. It is back now. Working on putting in better configurations to prevent that from happening in the future.
