Add dynamic key, value pairs to JavaScript array or hash table

Question

I\'m trying to add a key value pair to an existing javascript associative array. The key needs to be a variable. This is for JSON encoding. I realize there are many plugins

Answer 1

The following code will help you

ary.push( {[name]: val} );

See below example

let allData = [{name: "Cat", type: "Animal"}]
let finalData: any = [];
for (let i = 0; i < allData.length; i++)
{
  let obj = allData[i];
  for (let KEY in obj)
  {
    //Pushing data to other array as object
    this.finalData.push({ [KEY] : obj[KEY] });
  }
}
