How to use /execute Command in Minecraft 1.16-1.19.3 (Java Edition, PC)

The /execute command can be used to create all sorts of machines using setblock execute chains. In the video, I'll be going over how to use the execute command and how to make the execute command execute commands only at certain periods of an entity's appearance- allowing you to make all sorts of interesting command creations.
-------------------------------------------------------------------------
***Here's the commands used in the video***
-------------------------------------------------------------------------
/execute at @e[type=snowball] run summon tnt ~ ~3 ~ {Fuse:30}

/execute at @e[type=arrow] run setblock (where you want the redstone block to be) redstone_block

/execute at @e[type=arrow] run summon tnt

/kill @e[type=arrow]

/setblock (where your redstone block is) air

Thanks for watching the video, and if you have any questions about the execute command, feel free to comment them on this video! I will try to answer all questions as soon as possible.

Im wondering if it's possible to make something similar to /pt thor command from the Essentials plugin (iirc), it let your weapon to strike a lightning bolt on any block you were facing.

"Now, this command is useful for other things apart from mass chicken murder" 😂

[JamAttack]

how come the {fuse:value} part does nothing for me? I typed the command exactly the same but with myself instead of snowballs.
EDIT: Never mind, apparently I just didn't capitalize Fuse

Very helpful crashed my server by making snowballs summon snowballs XD

Thx I made bedwars with working fire balls just a snowball but it is fire ball

I have a question: if i want to summon a tnt when the arrow hits a mob, it's possible? I'm asking this because when you hit a entity, the arrow disappear (and the command only works to arrows who don't hit a mob)
