"New to coding—what is a syntax in computer programming?"

hey everyone! total noob here lol.

i keep hearing about "syntax" when i try to code, but like... what is a syntax in computer programming exactly?

is it just the rules for how to write code? why does it matter so much?

also, why do i get errors when i forget a semicolon or something? feels like the computer’s being picky af.

would love a simple explanation—maybe even an ELI5 version if possible!

thanks in advance

(ps. sorry if this is a dumb question, still figuring things out!)
