}

for (let z=0;z<arr.length;z++){

newArr=newArr.concat(arr[z]);

}

for(var y = 0;y < newArr.length;y+=2){

Below is the correct code to parse the input and output the data in required mentioned format : -

There are some modification done in the above provided code to make it correct , see below code-

===============================CODE START =====================================

const parser=(d)=>{

let arr=[];

let newArr=[];

let finalarry = []; /* Declared to store the final output , as output needs to be in array of objects format*/

let items=d.split('|');

for (let i=0;i<items.length;i++){

arr[i]=items[i].split(',');

}

/* Modification in below loop , as now it start from index 1 , because in array - arr[0] position headers are present */

for (let z=1;z<arr.length;z++){  

newArr=newArr.concat(arr[z]);

}

/* Modification in below loop */

for(var y = 0;y < newArr.length;y+=2){
let obj={} ; /* define obj within loop */   
obj[arr[0][0]] = newArr[y]; /* arr[0][0] and arr[0][1] contains the header name */
obj[arr[0][1]] = newArr[y+1];

finalarry.push(obj); /* push the created object in final array */
}

//const res = newArr.reduce((a,b)=> (a[b]='',a),{});

return finalarry; /* return the final array */

}

const data = `firstName, lastName | moe, green|lucy, liu|ethyl, mertz`;

console.log(parser(data));
