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?
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 ,.
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
}, [])
);
