NodeJS - String to array set

Question

I have a string set of -

"uid:ID1,name:Name1,uid:ID2,name:Name2"

I want to map "uid:ID1,name:Name1" into

The following format

{
uid :'ID1',
name: "Name1"
}

But for it to make as many property sets as are passed in via the string set.

So for the input string with "2 sets" I need it to make this following output.

 {
 uid :'ID1',
 name: "Name1"
 },
 {
 uid :'ID2',
 name: "Name2"
 }
 

What can I try?

Answer 1

Use the main function below:

const main = str => {
 // split on each comma
 const arr = str.split(',');
 // put back elements by pairs
 const pairs = [];
 for (let i=0; i<arr.length; i+=2) {
 let o = {};
 o.uid = arr[i].split(':')[1];
 o.name = arr[i+1].split(':')[1];
 pairs.push(o);
 }
 return pairs;
}
console.log(main('uid:ID1,name:Name1'));
console.log(main('uid:ID1,name:Name1,uid:ID2,name:Name2'));

This assumes that the input string is well-formed as a repetition of uid:...,name:... (no arbitrary key, no optional key) joined by ,.

Answer 2

Assuming that you want Objects and the keys are arbitrary...

console.log(
 "uid:ID1,name:Name1,uid:ID2,name:Name2"
 .split(/[,:]/)
 .reduce((res, val, i, arr) => {
 if (i % 4 === 0) {
 res.push({})
 }
 if (i % 2) {
 res[res.length - 1][arr[i - 1]] = arr[i]
 }
 return res
 }, [])
);
