Re: Are variables immutable?

[DENIS <denis@...>]

variable is just a label to a memory address.

see more below:

Immutability of strings

Lua strings are immutable and interned. This has some implications [4]. To create a string that differs in only one-character from an existing 100 MB string requires creating an entirely new 100 MB string since the original string cannot be modified.

Lua noob here! Reading Lua primer at learnxinyminures.com to start

It says that Lua variables are immutable like in Python. However,
in the Lua REPL, I can change any value I set. Maybe I should be
reading a more recent tutorial? TIA ...
