How to avoid “too many parameters” problem in API design?
...
I have been converging to this style more over time. Apparently significant amount of the "too many parameters" issues can be resolved with good logical groups and abstractions. In the end it makes the code more readable and more modularized.

When do you use POST and when do you use GET?
...t operation is one in which the result will be the same no matter how many times you request it.
It stands to reason that, as GETs are used for safe operations they are automatically also idempotent. Typically a GET is used for retrieving a resource (a question and its associated answers on stack ...
iOS Tests/Specs TDD/BDD and Integration & Acceptance Testing
...Xcode. This means it's simple to make a new test target, and, most of the time, getting tests up and running "just works."

setTimeout(() => console.log(x)) // closes over the `x` which is logically positioned at the top of the en...
Are there legitimate uses for JavaScript's “with” statement?
...his can lead to errors:
for (var i=0; i<3; ++i)
{
var num = i;
setTimeout(function() { alert(num); }, 10);
}
Because the for loop does not introduce a new scope, the same num - with a value of 2 - will be shared by all three functions.
A new scope: let and with

Less flexible: Sprocs can take full advantage of a database's featureset. LINQ tends to be more generic in it's support. This is common in any kind of language abstraction (e.g. C# vs assembler).
