for(var i = 0; i < 4; i++)
{
// Code to be repeated 4 times
}
Students will be able to:
In this lesson, students will learn about conditions and if statements. A condition is a function that returns a true/false answer. JavaScript uses if statements as a way to make decisions and execute specific code. If statements are helpful in writing code that can be used in different situations.
Students will be able to:
In this lesson, students will take a deeper look into conditional statements, more specifically if/else statements. If/else statements allow for one thing to be done if a condition is true, and something else otherwise.

if(frontIsClear()) {
// code to execute if front is clear
} else {
// code to execute otherwise
}
Students will be able to:

Students will be able to:
In this lesson, students take a look at all of the control structures. Control structures can be selective, like if and if / else statements and are based on a condition. Other control structures are iterative and allow for repeated code like for loops and while loops. Basically, control structures control the way the commands execute.
Students will be able to:
Debugging is a very important part of programming. In this lesson, students learn how to effectively debug their programs.

Students will be able to:
In this lesson, students will learn the proper way to indent their code. Indentation is especially important when using multiple loops, functions, and if statements to show the structure of the code.
