REST metadata fields generation

Question

I wrote a code to fetch the data present and store it in Array format but I thing I have wrote code multiple times can It be possible to minimize the code as its too long

let topicsValue = ["requiredType.*", "Entry.*", "token.*", "RestAPI.*"];
let Topic = [],
 rest = ["required", "unrequired"],
 final = ["createInput", "mustPossible", "finalOutput"];
topicsValue.map((data) => {
 let requiredType, entries, token, restAPI;
 if (data.split(".")[1].includes("*")) {
 if (data.split(".")[0].includes("requiredType")) {
 for (const value of final) {
 requiredType = data
 .split(".")[0]
 .replace("requiredType", "required_type")
 .concat(`.${value}`);
 Topic.push(requiredType);
 }
 }
 if (data.split(".")[0].includes("Entry")) {
 for (const value of final) {
 entries = data
 .split(".")[0]
 .replace("Entry", "entries")
 .concat(`.${value}`);
 Topic.push(entries);
 }
 for (const value of rest) {
 entries = data
 .split(".")[0]
 .replace("Entry", "entries")
 .concat(`.${value}`);
 Topic.push(entries);
 }
 }
 if (data.split(".")[0].includes("token")) {
 for (const value of final) {
 token = data
 .split(".")[0]
 .replace("token", "tokens")
 .concat(`.${value}`);
 Topic.push(token);
 }
 for (const value of rest) {
 token = data
 .split(".")[0]
 .replace("token", "tokens")
 .concat(`.${value}`);
 Topic.push(token);
 }
 }
 if (
 data.split(".")[0].includes("RestAPI") &&
 !data.split(".")[0].includes("RestAPIAction")
 ) {
 restAPI = data
 .split(".")[0]
 .replace("RestAPI", "restAPI")
 .concat(`.deploy`);
 Topic.push(restAPI);
 }
 } else {
 if (data.split(".")[0].includes("requiredType")) {
 if (!rest.includes(data.split(".")[1])) {
 requiredType = data
 .split(".")[0]
 .replace("requiredType", "required_type")
 .concat(`.${data.split(".")[1]}`);
 Topic.push(requiredType);
 }
 }
 if (data.split(".")[0].includes("Entry")) {
 if (rest.includes(data.split(".")[1])) {
 entries = data
 .split(".")[0]
 .replace("Entry", "entries")
 .concat(`.${data.split(".")[1]}`);
 Topic.push(entries);
 } else {
 entries = data
 .split(".")[0]
 .replace("Entry", "entries")
 .concat(`.${data.split(".")[1]}`);
 Topic.push(entries);
 }
 }
 if (data.split(".")[0].includes("token")) {
 if (rest.includes(data.split(".")[1])) {
 token = data
 .split(".")[0]
 .replace("token", "tokens")
 .concat(`.${data.split(".")[1]}`);
 Topic.push(token);
 } else {
 token = data
 .split(".")[0]
 .replace("token", "tokens")
 .concat(`.${data.split(".")[1]}`);
 Topic.push(token);
 }
 }
 if (
 data.split(".")[0].includes("RestAPI") &&
 !data.split(".")[0].includes("RestAPIAction")
 ) {
 restAPI = data
 .split(".")[0]
 .replace("RestAPI", "restAPI")
 .concat(`.deploy`);
 Topic.push(restAPI);
 }
 }
});
console.log(Topic);

Is there any possible way I can reduce the code without effecting the output

As the requirement of the code is like if the topicValue contain * or the other value so I wrote this long code and now I am trying to minimize the code so its look short and effective.

From a short review;

• jshint shows zero issues, congratulations ;)
• topicsValue should be const
• topicsValue could be topicValues
• managing entries without a wildcard seems way too complicated
• a lot of things are copy-pasted instead of declared once (like the mapping)
• a few more things could be const instead of let (rest, final)

Mandatory rewrite;

const topicValues = ['requiredType.*', 'Entry.*', 'token.*', 'RestAPI.*', 'RestAPIAction.Example'];
function createTopics(topicValues){
 
 const basic = ['createInput', 'mustPossible', 'finalOutput'];
 const extra = ['required', 'unrequired'];
 let topics = [];
 const maps = {
 requiredType: { to: 'required_type', values: basic }, 
 Entry: { to: 'entries', values: basic.concat(extra) }, 
 token: { to: 'tokens', values: basic.concat(extra) }, 
 RestAPI: { to: 'restAPI', values: ['deploy'] }, 
 }
 for(const topicValue of topicValues){
 const parts = topicValue.split(".");
 const topic = parts[0];
 const value = parts[1];
 if(value === "*"){
 topics = topics.concat(maps[topic].values.map(value=>`${maps[topic].to}.${value}`));
 }else{
 topics.push(topicValue);
 }
 }
 
 return topics;
}
console.log(createTopics(topicValues));
