I am new to verilog and trying to figure out where the function can be defined/declared in verilog (like I know function can be defined in packages, what else?). Thanks in advance.

In Verilog, a function can be declared between
module and endmodule (ie in the current region of a module - inside a module, but outside an initial or always block)
generate and endgenerate
That's it.
In System-Verilog, a function can be declared between
module and endmodule
generate and endgenerate
and
class and endclass
interface and endinterface
checker and endchecker
package and endpackage
program and endprogram
and
outside a module / interface / checker / package / program

Probably, easiest way to declare and use function is like, declare all your functions in <module_function_pkg>.vh and include that to design verilog file.
Use it as #dave_59 said in comment.

I'm new to CUDA, and so far all the tutorials I've seen are for arrays.
I am wondering if you can define something like double variable on CUDA, or does something like that have to live on the CPU?
You can have scalar variable as a kernel parameter, as a private variable, as a shared memory variable and even as a global compilation unit variable.
You can have scalar fields in classes, array of structs, struct of arrays, anything that uses a plain old data. You can use typedef, define macro and any bit level hacking as long as the variable is loaded/stored with proper alignment.

I want to understand what is Context in go gin , i see a lot of functions written which accept context as a parameter but dont see it passed anywhere or instantiated anywhere ? , can someone explain how it works
The gin Context is a structure that contains both the http.Request and the http.Response that a normal http.Handler would use, plus some useful methods and shortcuts to manipulate those.
The gin engine is responsible for the creation (and reuse) of those contexts, in the same manner as the http.Server is responsible for the creation of the http.Request objects a standard http.Handler would use.
The context is passed by the engine to its handlers, and it's your job to write those handlers and attach them to a router. A gin handler is any function that takes a gin.Context as its sole argument and doesn't return anything.

could any one please explain the differences between the bound imports and delayed imports in PE header.I have referred few books but i cannot get to understand the concept of it clearly.can anyone help me out.
Bound imports means that in PE-import table store fixed (bound) addresses of import functions for a specific version of DLL with those function. Bound addresses are calculated and written to import table by linker during program compilation and linking phase.
Delayed imports means that in import table instead of import functions addresses contains addresses of a special program part called "delay load helper" (sometimes is called also "thunk"), which substitutes real imported function address when the function is called for the first time. And subsequent function calls use real function address written by delay load helper.
It is the concept. Details you can find in Iczelion's PE tutorial, for example

I add linters for js (es6) in my project, and for new configurations I found that they prevent using const inside functions - only for module-level constants. And inside functions I should use let. But I can't find any ground for such rule. Why?
For jscs it's for example
disallowConstOutsideModuleScope: const should only be used in module scope (not inside functions/blocks)
I understand that I can configure and switch off that rule, I just wonder what for it was enabled ? What is the motivation for such checking?
P.S. I have link https://madhatted.com/2016/1/25/let-it-be with block "Constantly const"
There is another school of thought on when to use let and const I’ll need to address. This strategy suggests developers use const as much as possible. Any variable that is not re-assigned should be declared with const.
I think this usage is poor practice. It adds an extra distraction to the process of programming, and results in code difficult to understand and change.
But I can't find that arguments valuable
It's just a coding guideline. They follow this school of thinking. If you do not wish to use it, feel free to turn it off in your .jscsrc file. Main points are:
Aggressive use of const devalues the operator
Choosing const first really means choosing to think about every declaration. Will the next line of code change this assignment? How
will I use this variable?
There is no known performance difference between let and const.

Lets say I have some inputs and I'm generating some output.
I don't need to maintain state.
Should I use a function or should I create a class that will have one method that
would look exactly like that function?
What are the advantages of one over the other?
(besides unit testing which is easier with the object)
Coming from a Java background, this question is like asking if you should create a static final "Utils" class, a service class to inject, or a "smart" data carrier with behaviour.
Just as a personal opinion, generally, if the methods truly are stateless, it's just easier and simpler to create a static final "utils" class.
But as someone pointed out in the comments above, it's as broad as long, really.
