Better Commands

I Think that some commands should have more user friendly code, like the enchant command, you could have 
/give @p diamond_sword{Enchantments:[{id:sharpness,lvl:1000}]}

or you could do 

/give @p diamond_sword sharpness 1000

and for multiple enchants
/give @p diamond_sword sharpness,1000,looting,1000

and for effects you could do 

/speed 1 10 for /effect give @p minecraft:speed 1 10

same thing with jumpboost

/jump @p 1 10   

it just would make it easier for newer players and players that dont understand java that well.
