Whats the difference between i++ and i += 1 in this context 

for(var i = 0; i < list.length; i++);
for(var i = 0; i < list.length; i += 1);

Hi Ricardo,

In the context you gave, both actions would just increment variable i by one.

Both are a type of shorthand, both would be legal.. i++ would be seen more often, though.

Take care! -- Cal

i think i++ means: i will be increased by 1 AFTER all the statements inside the for loop executed (for a round). It might be significant in a case where you have a conditional statement to break the loop when i reaches a desired value.
