Answer 1

Akash Agrawal the "return true" code is returning the function provided as parameter for arr.forEach not the show function. If you want to return true try this:

for (let i of arr)
if (i==5) return true;

See more about array. forEach here:

Answer 2

Because your function is not returning anything.

Thanks VEDANG

Answer 4

VEDANG but why my function is not return true

Answer 5

A forEach loop cannot be broken before completion. You can use a traditional for loop as VEDANG suggested. Or use recursion
