why does the let variable display an error when you put it more than once?

i thought that since we're using it when we want something to keep changing, it would make sense to have it work when you put more than one?

Instead of using the let keyword each time you use the variable, try

let someValue = 1;
someValue = 2;

where you declare the variable once and just use the variable name afterwards.

you may declare a variable only once. Afterward you may reassign a value to the variable, but without using a keyword like let or const.
