An element inside an array can be of any type, and different elements of the same array can be of different types : string, boolean, even objects or other arrays.
Is the first element of an array 0 or 1?
Zero-based array indexing is a way of numbering the items in an array such that the first item of it has an index of 0, whereas a one-based array indexed array has its first item indexed as 1. Zero-based indexing is a very common way to number items in a sequence in today’s modern mathematical notation.
What does array I 1 mean?
In short, array[i – i] gives you the value of the element at the index 1 less than i. Your code does not generate those values. It either generates 40-160, or just 40, for index 1-4 in gearSpeeds.
What is a [- 1 in array?
If you access a Lua array with an index of -1, it will read the last element of the array.
Can you put an array inside an array?

How to create an array in one line?
Here are two compact code sequences to generate the N -element array [0, 1., N-1]: Array.apply (null, {length: N}) returns an N -element array filled with undefined (i.e. A = [undefined, undefined.] ). A.map (Function.call, Number) returns an N -element array, whose index I gets the result of Function.call.call (Number, undefined, I, A)
