An array arr is known to contain only integers from $0$ to N$-1.$ We declare

const freq $=$ new Array$($N$).$fill$(0)$;

Which of the following lines of code checks that arr is a permutation of the numbers from $0$ to N$-1?$

$(1)$ assert$($arr$.$length $===$ N$)$;

$(2)$ arr.forEach$($e $=>$ assert$(++$freq$[$e$]===1))$;

$(3)$ assert$($freq$.$every$($e $=>$ e $===1))$;
