Quoting man bash:
Command substitution allows the output of a command to replace the com-
mand name. There are two forms:
$(command)
or
‘command‘
Bash performs the expansion by executing command and replacing the com-
mand substitution with the standard output of the command, with any
trailing newlines deleted. Embedded newlines are not deleted, but they
may be removed during word splitting.
