if syntax: if([condition]){[code]}
for syntax: for(var [name]=[initial state];[condition];[increment]){[code]} while syntax: while([condition]){[code]}

An if statement checks if the condition is true, if so it does the select code, you can add else to the end to do something else if the statement is not true. A for statement loops through the block of code and checks at the end if the condition is true, if it is it loops again, otherwise it ends. A while statement does the select code while the condition is true, this is useful to do thing like remove whitespace from strings if you do not know how much whitespace is on the start/end of the string.
