I am fetching API into my Express server which has several JSON key value pairs in one array. For Example:
[{
"quality": "best",
"url": "https://someurlhere.example/?someparameters"
},
{
"quality": "medium",
"url": "https://someurlhere1.example/?someparameters"
}]
And I want to create an array of JSON of that received data in this Format:
[{
"best": "https://someurlhere.example/?someparameters"
},
{
"medium": "https://someurlhere1.example/?someparameters"
}]
I have tried doing this by using for loop
for(let i=0; i < formats.length; i++){
arr.push({
`${formats[i].quality}` : `${formats[i].url}`
})
}
But it didn't work for me.
Please help me in achieving this. Thanks in Advance :)
You could use the map function and create a new object from it.
For example:
let prevArr = [{
"quality": "best",
"url": "https://someurlhere.example/?someparameters"
}, {
"quality": "medium",
"url": "https://someurlhere1.example/?someparameters"
}]; // Replace with your array
let newArr = [];
let obj = {};
prevArr.map(function(x) {
obj = {};
obj[x["quality"]] = x.url;
newArr.push(obj);
});
const input = [{
"quality": "best",
"url": "https://someurlhere.example/?someparameters"
}, {
"quality": "medium",
"url": "https://someurlhere1.example/?someparameters"
}];
const result = input.map((v, i) => {
return {
[v["quality"]]: v["url"]
}
});
console.log(result)
