javascript adding object to an array

Question

this.journeyIds = ["source", "destination"];

It seems that you want the id as key of an object. Use [] around the id

this.journeyIds = ["source", "destination"];
this.journeyDetails = [];

this.journeyIds.map((id) => {
                this.journeyDetails.push({[id] :
this.el("#"+id).inputValue});
            });

I don't have the function this.el() so it's an array here, you could just replace it with the function call (this.el["#"+id].inputValue => this.el("#"+id).inputValue

this.journeyIds = ["source", "destination"];
this.journeyDetails = [];
this.el = {
  "#source": {inputValue: "foo"},
  "#destination": {inputValue: "bar"}
}

this.journeyIds.forEach((id) => {
    let temp = {};
    temp[id] = this.el["#"+id].inputValue;
    this.journeyDetails.push(temp);
});

console.log(this.journeyDetails)
