Tips for effectively generating a JSON object array in Typescript

Currently, I'm attempting to construct an array of JSON objects using TypeScript. Here is my current method:

const queryMutations: any = _.uniq(_.map(mutationData.result, function (mutation: Mutation) {
    if (mutation && mutation.gene) {
        const item = { facet: "MUTATION", term: mutation.gene + " " + mutation.proteinChange };
        return item;
    } else {
        return {};
    }
}));

const jsonString = JSON.stringify(queryMutations);

I would like to know if this approach is the most effective way to achieve this task. Any suggestions or feedback are greatly appreciated.

Answer №1

It appears satisfactory to me. Personally, I would suggest making some adjustments to the layout style and utilizing backtick placeholder strings.

   var queryMutations:any = 
        _.uniq(
          _.map(
            mutationData.result,   
            function(mutation:Mutation) {
              if (mutation && mutation.gene) {
                return {facet: "MUTATION", 
                        term: `${mutation.gene} ${mutation.proteinChange}`
              } else {
                return {};
              }
            }
          )
        );

    var jsonString = JSON.stringify(queryMutations);
