SameValue differs from the Strict Equality Comparison Algorithm in its treatment of signed zeroes and NaNs: +0 === -0 and !(NaN === NaN)
SameValueZero differs from SameValue only in its treatment of +0 and -0.

Countries have their own entry and exit requirements for children. The consent letter may not be considered sufficient by a country’s immigration authorities and there is no guarantee that they will recognize it. For more information, check the entry and exit requirements in the Travel Advice and Advisories for your destination country or contact the nearest embassy or consulate of the destination country before travelling. For example, to check for requirements for America , can send a letter to armcanadaembassy@mfa.am such as:
hi, armembassycanada.ca: If my child will travel to America without myself, is there a consent form to submit ONLINE indicating her/his temp guardian as my friend when she/he is in America? thanks

On writing this document, we're using 5.4.0 and it requires:
If the Hyperscan library is used on x86 systems without SSSE3, the runtime API functions will resolve to functions that return HS_ARCH_ERROR instead of potentially executing illegal instructions.
To build an AVX512VBMI runtime, the CMake variable BUILD_AVX512VBMI must be enabled manually during configuration(-DBUILD_AVX512VBMI=on).
Patterns are provided to a compilation interface which generates an immutable pattern database. The scan interface then can be used to scan a target data buffer
the target data consists of a list of non-contiguous blocks that are available all at once. As for block mode, no retention of state is required(Streaming mode requires retention of states).
some state space is required to store data that persists between scan calls for each stream. This allows Hyperscan to track matches that span multiple blocks of data.
scanning /foo.*bar/ against fooxyzbarbar will return two matches from Hyperscan. at the points corresponding to the ends of fooxyzbar and fooxyzbarbar. In contrast, libpcre semantics by default would report only one match at fooxyzbarbar (greedy semantics) or, if non-greedy semantics were switched on, one match at fooxyzbar. This means that switching between greedy and non-greedy semantics is a no-op in Hyperscan.
To illustrate, here is an example combination expression: ((301 OR 302) AND 303) AND (304 OR NOT 305) If expression (zxxu:with ID) 301 matches at offset 10, the logical value of 301 is true while the other patterns’ values are false. Hence, the whole combination’s value is false. Then expression 303 matches at offset 20. Now the values of 301 and 303 are true while the other patterns’ values are still false. In this case, the combination’s value is true, so the combination expression raises a match at offset 20. Finally, expression 305 has matches at offset 30. Now the values of 301, 303 and 305 are true while the other patterns’ values are still false. In this case, the combination’s value is false and no match is raised.
The version of Hyperscan used to produce a compiled pattern database must match the version of Hyperscan used to scan with it.
Using the SOM flag entails a number of trade-offs and limitations:
