Why is ArrayDeque better than LinkedList
...ian.
The test setup considers:
Each test object is a 500 character String. Each String is a different object in memory.
The size of the test array will be varied during the tests.
For each array size/Queue-implementation combination, 100 tests are run and average time-per-test is c...
Best practice for embedding arbitrary JSON in the DOM?
...
This wouldn't work for a single string, e.g. "I am valid JSON" and using double quotes for the tag, or single quotes with single quotes in the string, e.g. data-unicorns='"My JSON's string"' as single quotes aren't escaped with encoding as JSON.

Differences between C++ string == and compare()?
...class charT, class traits, class Allocator>
bool operator==(const basic_string<charT,traits,Allocator>& lhs,
const basic_string<charT,traits,Allocator>& rhs) noexcept;
Returns: lhs.compare(rhs) == 0.
Seems like there isn't much of a difference!

Round to at most 2 decimal places (only if necessary)

// It changes the result (which is a string) into a number again (think "0 + foo"),
// which means that it uses only as many digits as necessary.
It seems like Math.round is a better solution. But it is not! In some cases it will NOT round correctly:
