== is to test if something equals something else
= is to SET SOMETHING to SOMETHING ELSE.

sets x to y and then returns y. The while loop then checks the returned value (y) for truth. That's how simple it is. Another example would be
--- Code: ---%x = %y = %z;

so basicaly...

so...
$a = 0;
$b = 1;
$a = $b = 2;
would set everything to 2
in your while loop example, it's returning 1 which is true, and forms the infinite loop
edit: and echo($a = "hi"); echos hi

It may in certain circumstances.
for example:
let's say player.addHealth will return the resulting health
if(isObject(player) && player.getDatablock().getName() $= "PlayerTest")
The functionality will not change, as getDatablock is strictly for returning data. In fact, you want it to short circuit because you don't want that .getdatablock returning an error if player doesn't exist.
however
if(player.getDatablock().getName() $= "PlayerTest" && player.addHealth(25) >= 80)
The player will never gain the health if they aren't the PlayerTest datablock.

Oh my gosh, even Ipquarx had to correct someone.
