React hook to check element sizes and do it in 1 render cycle so in the next one they can be covered by preloader/sekeleton component using the sizes
import { useState, useEffect, useRef } from 'react'
/**
* This hook provides an array of refs with a fixed length.
* Then you can set the refs to any of your elements and on the next render tick, you will now size of such elements.
*
* Example of usage:
*
* const reservedQuantityOfElements = 2
* const [elementsToBeSized, elementsSizes, temporaryShowElementsAsIs] = useElementsSizes(reservedQuantityOfElements)

Switch ssh credentials to use another key for git when you use multiple accounts and return back
# to switch:
ssh-add -D && ssh-add ~/.ssh/id_rsa_personal
ssh-add -D && ssh-add ~/.ssh/id_rsa
ssh-add -D && ssh-add ~/.ssh/id_rsa_gmail
# to generate such file:
ssh-keygen -t ed25519 -C "dmitry.loburets@gmail.com" -f ~/.ssh/id_rsa_gmail
