"[ - abc=10 ]" vs "[ – abc = 10 ]"

Question

How are they different?

I am using the [ command. I know we need a space after [ and before ], and that the test command is equivalent. But I can't find any information about the difference between the expressions

[ abc=10 ] and
[ abc = 10 ]

Is that an en dash? And not even an ASCII hyphen? Is that the name of some command or what is it supposed to be? — ilkkachu, Nov 13 '17 at 23:03
For starters, – abc=10 is two words and – abc = 10 is four words. If passed to a command, the former results in two arguments and the latter results in four arguments. — AlexP, Nov 14 '17 at 07:36
I believe that it’s clear what the question is asking — but isn’t this a duplicate of, like, 42 other questions? — G-Man Says 'Reinstate Monica', Nov 10 '18 at 23:52

abc=10 will set the variable abc equal to 10.

abc = 10 will execute abc with parameters = and 10.

Not within [...], which is what I believe the user means, judging from the title. – Kusalananda Nov 10 '18 at 22:52
To be fair, there were no brackets in the title when this answer was posted. – G-Man Says 'Reinstate Monica' Nov 10 '18 at 23:55
