php - What's the point of javascript templating engines? -


I know people generally answer, but I need a solid example of why they are necessary.

I'm getting the latest impressions (mostly from underscore .js) is that it creates code and php, such as you & lt; %%> like?> In PHP

The idea is to create less spaghetti for my code and there is a clear difference between presentation and logic. This is what everyone says, but I'm not sure why this warrants the need for a templating engine.

Why can not you just do this in pure JavaScript? You have only one function that takes data as a logic and you can have javascript syntax without searching for a new language, which seems ridiculous. For example, you can just do this: 

  populateTable (obj) {$ ('#models'). Html ('& lt; h2 & gt;' + obj.title + '& lt; / h2 & gt;' + & lt; ul & gt; ...  & gt;}

This sounds good to me, it's a function that you are dedicated to presenting in the table using some model data. Do we need to invent new syntax?

One of the reasons for me is that I like to write: 

  Lt; div class = "entry"> 
 {{title}} 
 
 {{body}} & lt ; / 
 
  var createEntryTemplate = function (obj) {w '' 'L' div 
 Title + '& lt; / h1 & gt;' + '& lt; div class = "body" & gt; + + obj.body +' 
 & # 39; & # 39; + & lt; / div & The second method is  more error prone  - if it's not for you, maybe for someone else. There is not enough programming experience and it needs to go to HTML and change its important part 
 
 Oh nonsense ...

ios - How do I use CFArrayRef in Swift? -

I am using Objective-class in my Swift Project through a bridging header. The method signature looks like this: - Some cement (some type) some parameters; I started by getting an example of class, calling method, and storing the value: var myInstance = MyClassWithThatMethod (); Var cfArr = myInstance.someMethod (some value); Then try to get the value in the array: var valueInArrayThatIWant = CFArrayGetValueAtIndex (cfArr, 0); However, I get the error unmanaged & lt; Cfarray & gt; Not like 'CFArray' . Unmanaged & lt; Cfarray & gt; also means? I looked, but I do not need to change the array in a fast array (though it would be good). I need to be able to get value from the array. I also tried CFArray method to pass in a function: func doSomeStuffOnArray (myArray: NSArray) {} Although I get the same error when using: doSomeStuffOnArray (cfArr); // unmanaged & lt; CFArray & gt; I am using CFArray because I want to sto...
