To add an element to an array in Lua, you can use the table.insert function. This function has two arguments: the table to which the element should be added and the value of the element itself. For example:
-- Define an array
myArray = {"apple", "banana", "orange"}
-- Add a new element to the end of the array
table.insert(myArray, "kiwi")
-- Print the updated array
for i = 1, #myArray do
print(myArray[i])
end
In this example, we define an array called myArray with three elements. We then use table.insert to add a new element to the end of the array with the value "kiwi". Finally, we use a for loop to print out the updated array.
The output of this code would be:
apple
banana
orange
kiwi
You can also add an element at a specific index in the array by passing an additional argument to table.insert, which specifies the index at which the element should be added. For example:
-- Define an array
myArray = {"apple", "banana", "orange"}
-- Add a new element at index 2
table.insert(myArray, 2, "kiwi")
-- Print the updated array
for i = 1, #myArray do
print(myArray[i])
end
In this example, we use table.insert with an additional argument of 2 to add the element "kiwi" at index 2 of the array. The output of this code would be:
apple
kiwi
banana
orange
