Accumulator.: A variable used in a loop to add up or accumulate a result.
🔗
Loop Counter.: A variable used in a loop to count the number of times something happened. We initialize a counter to zero then increment the counter each time we want to “count” something.
🔗
Decrement.: To decrease the value of a variable (often by one).
🔗
Initialize.: To give an initial value to a variable that will be updated.
🔗
Increment.: To increase the value of a variable (often by one).
🔗
Infinite Loop.: A loop in which the terminating condition is never satisfied or for which there is no terminating condition.
🔗
Iteration.: One repeated execution of a set of statements using either a function that calls itself or a loop.
