Conditionals 1

Conditions are like questions. They allow a program to decide to take one action if the answer to a question is true or to do another action if the answer to the question is false. The questions asked within a program are always logical or relational statements. For example, if the variable 'i' is equal to zero then draw a line.

    // If 'i' divides by 20 with no remainder draw the first line
    // else draw the second line
    if (i % 20 === 0) {
      stroke(255);
      line(i, 80, i, height / 2);

      line(i, 20, i, 180);
