I have an array like this:
const faces= [
[[128516], "grinning face with smiling eyes", "20201001"],
[[128512], "grinning face", "20201001"],
[[128578], "slightly smiling face", "20201001"],
[[128579], "upside-down face", "20201001"],
[[128521], "winking face", "20201001"]
]
And I want to convert it to a formatted JSON like this using JavaScript:
[
{
"id": 128516,
"name": "grinning face with smiling eyes",
"date": "20201001"
},
{
"id": 128512,
"name": "grinning face",
"date": "20201001"
}
]
Any help is appreciated.
const faces = [
[
[128516], "grinning face with smiling eyes", "20201001"
],
[
[128512], "grinning face", "20201001"
],
[
[128578], "slightly smiling face", "20201001"
],
[
[128579], "upside-down face", "20201001"
],
[
[128521], "winking face", "20201001"
]
]
let result = []
faces.forEach(item => {
let a = {
id: item[0][0],
name: item[1],
date: item[2]
}
result.push(a)
})
console.log(JSON.stringify(result))You could use reduce:
const faces = [
[
[128516], "grinning face with smiling eyes", "20201001"
],
[
[128512], "grinning face", "20201001"
],
[
[128578], "slightly smiling face", "20201001"
],
[
[128579], "upside-down face", "20201001"
],
[
[128521], "winking face", "20201001"
]
]
const result = faces.reduce((result, value) => {
result.push({
id: value[0][0],
name: value[1],
date: value[2]
})
return result
}, [])
console.log(result)Simple one liner code using 'map' functionality of Arrays.
const faces= [
[[128516], "grinning face with smiling eyes", "20201001"],
[[128512], "grinning face", "20201001"],
[[128578], "slightly smiling face", "20201001"],
[[128579], "upside-down face", "20201001"],
[[128521], "winking face", "20201001"]
];
let newObj = [];
faces.map(eachObj => {
const obj = {
id: eachObj[0][0],
name: eachObj[1],
date: eachObj[2]
};
newObj.push(obj);
});
console.log('New Obj ==>', newObj);
