Variable functions definitions inside a loop?


Tag : javascript , By : Pradeep Gowda

around this issue Technically, you're defining a defining the functions 80 bajillion times or so in both versions. For high volumes of iteration, you should get some performance benefit from defining it like this.
var doSomething = function(index, element){
      $(element).whatever();
    };

return this.each(doSomething);

The Python assignment operator, function definitions, and variable definitions

hop of those help? As you've discovered, the = operator in Python doesn't make a copy of an object like it does in C++ for example. If you want to make a copy to store in another variable you have to be explicit about it.
board[1] = deck1[:]  # the slicing operator copies a subset or the whole list
import copy
board[1] = copy.copy(deck1)
board[1] = copy.deepcopy(deck1)

Deporting/moving UI router's resolve functions definitions outside of the state definitions

this one helps. Following the comments above, you can use a service to implement the business logic and call the service functions in the resolve block. This is possible as the resolve code is not executed as part of the config block but rather right before the state changes. You just inject the service to the function within the resolve block.
Here is an example, based on your code sample:
.state('authenticated', {
            url: '/:memberType',
            abstract: true,
            template: '<ui-view />',
            resolve: {
                memberType: ['MemberService', function(MemberService) { return MemberService.getMemberType(); }],
                currentMember: ['MemberService', function(MemberService) { return MemberService.getCurrentMember(); }]
            }
        })

A question on variable handling in asynchronous functions. Will this code cause inconsistency?


Tag : javascript , By : dnyaneshwar

wish of those help Yes, this may cause inconsistency if you somehow call this functions one after another without await. However you shouldn't.
Just call them like this:
await generatepassword();

await changepassword();

Base R - functions general question - Outputting a variable with an input name


Tag : r , By : Edo

I wish this help you Is there a way I can write an input name for a variable I want to output in a function? I currently have this very simple example: , This is just an assign trick. See help("assign").
power <- function(value1, value2, Variable_name) {
  Variable_name <- as.character(substitute(Variable_name))
  assign(Variable_name, value1 + value2, envir = .GlobalEnv)
}

power(value1 = 2, value2 = 3, Variable_name = SumofValues)

SumofValues
#[1] 5
