Luau isfrozen()

The isfrozen() function in the Luau programming language returns a boolean based on whether the table is in read-only mode or not. When a table is in read-only mode, it means that the contents can’t be modified, as a measure of data protection.

Syntax

isfrozen(table);

The isfrozen() function returns a boolean value, true if the table is in read-only mode and false if it’s not.

Example

In this example, a table called myTable is created. Then, the isfrozen() function is used to check if it’s in read-only mode.

-- Create a table
local myTable = {1, 2, 3}

-- Check if the table is initially frozen (read-only)
local frozenStatus = table.isfrozen(myTable)

-- Output the result
if frozenStatus then
    print("The table is frozen (read-only).")
else
    print("The table is not frozen (read/write).")
end
