For(var x =1; x<6;x++) If (x==3) X=6; Alert(x) Output is 7 Why would not it be 6?

Because x keeps iterating and the loop ends when x is greater than 6, and because you defined x as a global variable, it is available outside of the loop block.

Adding printouts and brackers might help understanding the code for( var x =1; x < 6; x++ ) { if (x == 3) { x = 6; } console.log( `in loop x = \${x}` ); } console.log( `out of loop x = \${x}` );

Evgeny Sergeev Answer would be 6 if there is break after x = 6 otherwise answer would be 7 because of x++ for(var x = 1; x < 6; x++) if (x == 3) { x = 6; break; } alert(x)

You reminded me of the joke about the eighth railway carriage 😃 - this is the one that immediately goes after the seventh, or the one before the ninth 🤣 Here is the sequence of the for() loop, check it out ☺️: var x = 1; for(; x < 6 ;){ if(x == 3) x = 6; x++; } alert(x);

X = 7 because When x = 3 You entered the if block, there x becomes 6. But, the for loop was running at that time. So the value of x get incremented at the end of for loop. That's why x becomes 7 /*********************************/ If you want the value of x = 6 Then use a break statement Write this way if(x==3) { x = 6; break; // the loop will terminate here immediately and value of x will not increment } Alert(x)

Solo loop finishes at 5 Idk math to get it 7 But when it hits 3 x becomes 6
