How to update the specific array element index position and specific array of object property in Javascript?. I have below mock data based on object property need to update their respective value using spread operator. I am not able to do that because it is nested.
I am able to achieve using below approach but as you can see code line is getting increased. But we can definitely reduce use spread operator. Because in “title” property i am only updating 0 index and in left column only updating the label value rest of the thing is same.
const mockData = {
title: [“Javascript”, “Selected Topic”],
leftColumn: [
{
key: “name”,
label: “Javascript Topic Name”,
type: “string”,
},
{
key: “id”,
label: “Javasctipt Topic Id”,
type: “string”,
},
],
};
const handleType = (val) => {
switch (val.type) {
case “Javascript”:
return {
…mockData,
};
case “Angular”:
return {
…mockData,
title: [“Angular”, “Selected Topic”],
leftColumn: [
{
key: “name”,
label: “Angular Topic Name”,
type: “string”,
},
{
key: “id”,
label: “Angular Topic Id”,
type: “string”,
},
],
};
case “React”:
return {
…mockData,
title: [“React”, “Selected Topic”],
leftColumn: [
{
key: “name”,
label: “React Topic Name”,
type: “string”,
},
{
key: “id”,
label: “Reacr Topic Id”,
type: “string”,
},
],
};
}
};
