Replace all values of a given key
View replaceValues.ts
* Return a copy of an object, but with values of a key replaced with value of provided key-value object.
* Useful for duplicating highly nested object, but generating new values for a key (e.g. `id`)
* @param obj An object
* @param keyToReplace The key of the values needed to be swapped
* @param mapOfOldToNewValues A key-value object with a keys of old values mapped to new ones (used for swapping)
* @example
View SuspenseRedirect.tsx
import { globalHistory, navigate, RedirectProps, History } from '@reach/router';
import React from 'react';
type ReachHistory = History & {
_onTransitionComplete: () => void;
* Why is `SuspenseRedirect` necessary when @reach/router has `Redirect`?

Stevey's Google Platforms Rant

I was at Amazon for about six and a half years, and now I've been at Google for that long. One thing that struck me immediately about the two companies -- an impression that has been reinforced almost daily -- is that Amazon does everything wrong, and Google does everything right. Sure, it's a sweeping generalization, but a surprisingly accurate one. It's pretty crazy. There are probably a hundred or even two hundred different ways you can compare the two companies, and Google is superior in all but three of them, if I recall correctly. I actually did a spreadsheet at one point but Legal wouldn't let me show it to anyone, even though recruiting loved it.

I mean, just to give you a very brief taste: Amazon's recruiting process is fundamentally flawed by having teams hire for themselves, so their hiring bar is incredibly inconsistent across teams, despite various efforts they've made to level it out. And their operations are a mess; they don't real

You can’t perform that action at this time.
