I am working with a JSON file that contains an array of 2 objects: `{ bg: 'a', o: 'c' }`, `{hg': 'a2', 'oo': 'c3'}`. My goal is to compare each object in the array with another object structured as follows: `{ fm: 'a', fh: 'b', o: 'a', fe: 'b', ft: 'a', fb: 'c', bg: 'f' }`. The objective is to identify if this reference object includes both sets of key/value pairs found in either of the objects within the JSON array. What would be the best approach for comparing these objects?
This method involves
Object.entries to access each key-value pair of an object in the form of [key, value].
Array.prototype.map to compare each entry (key-value pairs) against another provided object.
Array.prototype.every to check if all entries of an array-item match those of another provided object.
const sampleArr = [ { bg: 'a', o: 'c' }, {'hg': 'a2', 'oo': 'c3' } ];
const sampleObj = { fm: 'a', fh: 'b', o: 'a', fe: 'b', ft: 'a', fb: 'c', bg: 'f' };
console.log("### How `Object.entries` works ###");
console.log({
sampleArr
});
console.log(
"sampleArr[0] => Object.entries(sampleArr[0]) ...",
sampleArr[0], " => ", Object.entries(sampleArr[0])
);
console.log(
"sampleArr[1] => Object.entries(sampleArr[1]) ...",
sampleArr[1], " => ", Object.entries(sampleArr[1])
);
console.log("### Comparison 1 with what was provided by the OP ###");
console.log(
sampleArr
// create a new array which for each ...
.map(item => {
// ... `sampleArr` item retrieves/maps whether ...
return Object
.entries(item)
// ... every entry of such an item exists
// as entry of another provided object.
.every(([key, value]) => sampleObj[key] === value)
})
);
sampleArr.push({ o: 'a', ft: 'a', fh: 'b' }); // will match ... maps to `true` value.
sampleArr.push({ o: 'a', ft: 'X', fh: 'b' }); // will not match ... maps to `false` value.
console.log("### Comparison 2 after pushing two more items into `sampleArr` ###");
console.log({
sampleArr
});
console.log(
sampleArr
// create a new array which for each ...
.map(item => {
// ... `sampleArr` item retrieves/maps whether ...
return Object
.entries(item)
// ... every entry of such an item exists
// as entry of another provided object.
.every(([key, value]) => sampleObj[key] === value)
})
