Object internal reference declarations

Question

I\'m watching out for a shortcut way to use values from a dictionary as an internal reference inside the dictionary. The code shows what I mean:

var dict =          


        

Answer 1

You could use mustache and define your json as a "mustache template", then run mustache to render the template. Take into account you would need to run (n) times if you have nested dependencies. In this case you have 3 dependencies ABC --> AB --> A.

var mustache = require('mustache');

var obj = {
  A : 'A',
  AB : '{{A}}' + 'B',
  ABC : '{{AB}}' + 'C'
}

function render(stringTemplate){
  while(thereAreStillMustacheTags(stringTemplate)){
    stringTemplate = mustache.render(stringTemplate, JSON.parse(stringTemplate));
  }
  return stringTemplate;
}

function thereAreStillMustacheTags(stringTemplate){
  if(stringTemplate.indexOf('{{')!=-1)
    return true;
  return false;
}

console.log(render(JSON.stringify(obj)));

And the output is:

{"A":"A","AB":"AB","ABC":"ABC"}
