How to come back to the loop 1! …

[Obi-wan Kenobi]

Hi Scripters!

Beginning the run with a = 0, I don't know how to quit the level 4 if the "if" condition is OK with a = 0 and come back to the level 1 to play with a = 1!  

Thanks for your help!

for ( a = 0; a < A; a++ ) {
    // ----------------------------------------------------------------------------------------------------------------------------------
    for ( b = 0; b < B; b++ ) {
        // ----------------------------------------------------------------------------------------------------------------------------------
        for ( var c = 0; c < C; c++ ) {
            // ----------------------------------------------------------------------------------------------------------------------------------
            for ( d = 0; d < D; d++ ) {
                // ----------------------------------------------------------------------------------------------------------------------------------
                if // OK
                    continue;
            }
        }
    }
}

Hi Obi-wan Kenobi​,

deep nested loops are very time expensive. Try to avoid them.

If necessary, put them in functions like this example (back to level before loop a-A)

var a;
function loopInNestedLoops () {
    var A = B = C = D = 3;
    for ( a = 0; a < A; a++ ) {
        // ----------------------------------------------------------------------------------------------------------------------------------
        for ( b = 0; b < B; b++ ) {
            // ----------------------------------------------------------------------------------------------------------------------------------
            for ( var c = 0; c < C; c++ ) {
                // ----------------------------------------------------------------------------------------------------------------------------------
                for ( d = 0; d < D; d++ ) {
                    // ----------------------------------------------------------------------------------------------------------------------------------
                    if (a === 1) {// OK  
                        return a;
                    }
                }
            }
        }
    }
}
loopInNestedLoops ();

Have fun
