d3.csv promise pending and getting its data

This is my first time to ask StackOverflow - I'm new to D3 and had used v5 for this matter

I have already been searching for days and can't find anything. if there's an existing one please help me directly to an exact answer. thank you so much for the help!

intro: just got a sample data for use:

Wafer,N Rows,Product Yield,Endline Yield,Mid_Yield

7G650,10,91.18%,99.70%,94.27%

7G651,10,88.41%,98.11%,95.54%

7G652,10,92.08%,97.56%,98.58%

7G657,10,87.71%,97.76%,95.77%

first off - before, my code was like below:

<script src="https://d3js.org/d3.v5.min.js"></script>

<script type="text/javascript">

   $(document).ready(function() {

      var yield = d3.csv("http://server/trend/data.csv",

                       function(data, i) {

                          return {

                             waf : data.Wafer,

                             seq : i,

                           yield : +data["Product Yield"].replace(/%/g, "")

                       };

      });

      console.log(yield);

   });

</script>

and when I checked at the console (chrome) - I can see my data. it's just that it needs a promise implementation

enter image description here

so i searched for some solution and here's my code now:

var yield = d3.csv("http://server/trend/data.csv",

                function(data, i) {

                    return {

                         waf : data.Wafer,

                         seq : i,

                       yield : +data["Product Yield"].replace(/%/g, "")

                    };

                 }).then(function(data){

                       console.log(data);

             });

I could still see my filtered data from console.log(data),

enter image description here

but when I query from outside d3.csv using the "yield" variable

console.log(yield);

values are now undefined

enter image description here

so sorry for the trouble, my boss is about to kill me.. i will need this filtered data for my trend, and soon will add a pareto chart.. thanks in advance and more power to stackoverflow -

re: using yield / return as keys for object literals:

const test = {

  yield: 'yield',

  return : 'return'

}



const getTest = () => ({

  yield: 'getYield',

  return: 'getReturn'

})



const getTest2 = function(){

  return {

    yield: 'getYield2',

    return: 'getReturn2'

  }

}



console.log(test, getTest(), getTest2())

const test = {

  yield: 'yield',

  return : 'return'

}



const getTest = () => ({

  yield: 'getYield',

  return: 'getReturn'

})



const getTest2 = function(){

  return {

    yield: 'getYield2',

    return: 'getReturn2'

  }

}



console.log(test, getTest(), getTest2())

const test = {

  yield: 'yield',

  return : 'return'

}



const getTest = () => ({

  yield: 'getYield',

  return: 'getReturn'

})



const getTest2 = function(){

  return {

    yield: 'getYield2',

    return: 'getReturn2'

  }

}



console.log(test, getTest(), getTest2())

Still there is a yield in the object literal.

as a key? I didn't think there was anything wrong with it?

Good point. Never thought about that since I generally consider using a keyword as an identifier a bad idea. Related: mathiasbynens.be/notes/javascript-properties, "Rules for unquoted JavaScript Object Literal Keys?".

` ECMAScript 3 didn’t allow the use of unquoted reserved words as property names.` I see your point.

hi @pandamakes, thanks for your answer, i tried your code & changed all yield keyword except for csv-col-title var resultYield; d3.csv("http://localhost:5001/data.csv", function(data, i) { return { waf : data.Wafer, seq : i, yld : +data["SDPT Yield"].replace(/%/g, "") }; }).then(function(data){ resultYield = data; console.log(resultYield); }); resultYield works inside d3.csv, but not outside still- i need to get this kind of data --- resultYield = [{ waf: "7G650", seq: 1, yld: 94.27 }]
