It was added in ES2018 (spread for arrays/iterables was earlier, ES2015), but it's been supported in React projects for a long time via transpilation (as "JSX spread attributes" even though you could do it elsewhere, too, not just attributes). {...this.props} spreads out the "own...
It seems likely to me that the definition of chemosensitivity is also contingent and probabilistic - not immutable or deterministic. The intrinsic properties of the neuron may be like the genetic code, but synaptic events will determine how the ionic properties of CO_2 sensitive cells are ...
If the items in a tuple are mutable, then you’ll be able to change them even if the tuple itself is immutable. In other words, the immutability of Python tuples refers to the references it directly holds. It doesn’t extend to the referenced objects themselves. In general, putting mutab...
The declarative version might sound something like this: “Drive to Sue’s house.” One says how to do something; the other says what needs to be done. The declarative style has two advantages over the imperative style: It does not force the traveler to memorize a long set of instructio...
If a team is to reach its potential, each player must be willing to subordinate his personal goals to the good of the team. —Bud Wilkinson 50 The man in charge must concern himself with details. If he does not consider them important, neither will his subordinates. —Hyman Rickover ...
(BMI) does not distinguish fat from muscle, and it has been found thatAfrican Americans are likely to have less fat mass than White Americanswith the same BMI. This suggests that overweight and obesity ranges for African Americans should be higher than they are for White Americans. Another ...
The true answer to this question, indeed, perhaps only the very Truth knows: but this is what we, tracing out the truth so far as we are capable by conjectures and inferences, apprehend concerning the matter. Neither does the word of God lie when it says that man was made in ...
Objects of immutable type can be created with the use of the keywords "const" and "readonly". While readonly allows modification of a field within the constructor, const does not. Numbers, strings and null can only be used as const fields, which are truly immutable. Readonly is not truly...
We are spending far too much time expiring cache entries. This is easy to understand why with a second look at the code of theget()function: every cache lookup does old entry expirationand thensearches for a matching cache entry. The way cache-entry expiration works with an immutable HashMa...
Since distributed ledgers are immutable, transactions aren't reversible, which can be good or bad. The recipient of a payment doesn't need to worry about the sender performing a chargeback like they can with other payment methods. But this also means the sender has no recourse in the event ...
