Expressions In JavaFX

Block expression is surrounded by curly bracket:

var total = {

    var value = [1..10];

    var sum = 0;

    for( v in value){

        sum = sum + v;

    }

    sum;

}

If Else block:

var a = 4;

if(a>5){

println("4 is greater than 5");

}else{

println("4 is less than 5");

}

Range expression:

var seq = [1..100];

var seq2 = [1..100 step 2];
var seqDesc = [100..1 step -1];

For expression:

var data = [1..100 step 2];

for(d in data){

    println(d);

}

While expression:

var i = 0;

while(i<10){

    println(i);

    i++;

}
