Regarding the problem of adding data to table with table.insert

Question

arr={}

for i=1,100 do

-- print(i)

table.insert( arr , 1, i )

end

In the above code, when table.insert in Lua adds data to the table, why does the array structure become {100,99,98,.. ....,3,2,1} instead of {1,2,3,4....99,100}

Answer 1

Solved. When table.insert adds data to the table, it inserts the first position every time. That is, the table structure for the first cycle is {1}, and the structure for the second cycle is {2,1}. Three times {3,2,1}..., and so on

Answer 2

Because the data will not be returned until the loop is completed.

Answer 3

Try replacing --print(i) with ++print(i)
