How to generate javascript code multiple times depending on a variable?

Question

JavaScript

Connected the Gantt module to display Gantt charts. However, it is required to add lines of this module depending on the variable from the database. The example below creates one row for the first channel. Is there any preprocessor built into the code so that you can repeat this piece of code (in the source property) several times?

$(".gantt").gantt({
          source: [{
          					name: "Channel 1",
          					desc: "",
          					values: [{
          						from: "/Date(1320192000000)/",
          						to: "/Date(1322401600000)/",
          						label: "Requirement Gathering",
          						customClass: "ganttRed"
          					}]
          				},
                ],


                
          scale: "days",
          minScale: "hours",
          maxScale: "days",
          navigate: "scroll"
        });
