var n=25;
for(i=2;i<n;i++){
if(n%i==0){
console.log('this is not prime');
}
else{
console.log('this is prime');
}
}

Your code is not a MATLAB code
To do something like this in MATLAB
n = 25;
for i =1:n
if(mod(n,i)==0)
disp('this is not prime');
else
disp('this is prime');
end
end

The if condition is working the way you programmed it.
If you want to test for something being prime, you need to test for all of the non-prime possibilities first, and you should only display that the number is prime after you have finished ruling out the possibility of a divisor.
