TS2554 — Expected N Arguments But Got M

Apa penyebab error ini

You are calling a function with too many or too few arguments. Required parameters must always be provided. Rest parameters and overloaded functions can make the expected count unclear.

Cara memperbaikinya

Check the function signature for the correct number of parameters. Add missing arguments or remove extra ones. Mark parameters as optional with ? if they should not always be required.

function add(a: number, b: number) { return a + b; }
add(1);
