what's the défférence betwwen those codes , they print the same :

code1:

var num = 99;
while (num >=1) {
// Last iteration. Note occurances of bottle, bottle, bottleS
if (num === 1) {
console.log(num + " bottle of juice on the wall! "
+ num + " bottle of juice! Take one down, pass it around... "
+ (num-1) + " bottles of juice on the wall!");
}
// Second-last iteration. Note occurances of bottleS, bottleS, bottle
else if (num === 2){
console.log(num + " bottles of juice on the wall! "
+ num + " bottles of juice! Take one down, pass it around... "
+ (num-1) + " bottle of juice on the wall!");
}
// All other iterations. Note occurances of bottleS, bottleS, bottleS
else {
console.log(num + " bottles of juice on the wall! "
+ num + " bottles of juice! Take one down, pass it around... "
+ (num-1) + " bottles of juice on the wall!");
}
num = num - 1;
}

code 2:
var num = 99;

while (num >=1) {
console.log(num + " bottles of juice on the wall! "
+ num + " bottles of juice! Take one down, pass it around... "
+ (num-1) + " bottles of juice on the wall!");
}
num = num - 1;
}
