Can anyone explain that answer please?

Question

Var x=0 , y=0;
for( i=0 ; i <= 2; i++ )
{x = i ;
switch(x)
{case 0: y = 100 ;
case 1: y+= 10 ;
case 2 : y+= 1}
}
console.log(y)

Answer 1

1 - declares the variable
var x = 0, y = 0

2 - iterates through the loop as long as i is 2
for ( i = 0; i<=2; i++){

3 - Now x has the same value of i
x = i

4 - Init switch case
switch(x) // for x
{ case 0: y = 100; // if x is 0 then y is 100
case 1: y = 10 // if x is 1 then 10 is added to y
case 2: y = 1 // if x is 2 then add 1 to y
}

console.log(y) //output 123

The switch case goes futher, as long as the statement is true, in the other case statement, because there 's no break keryword. Therefore the output is 123
