Is this a good or bad thing to do

[Victor_Holly123 (XXG)]

So my friend codes like this (example):

local var = something
var = true
var = var

I want to know if setting a value to the same value does anything at all.

There is no point of using var = var since it is already the same value.
in short, it’s bad because it might affect the performance.
