I'd like to filter and restructure some specific data, but I'm having some trouble getting it to produce the proper structure.
I have this data response in this structure....
var response = {
badProperty1: "bad property text"
goodProperty1: "abc"
goodProperty2: "bcd"
goodProperty3: "cde"
goodProperty4: "def"
goodProperty5: "efg"
badProperty2: "fgh"
};
I'd like to convert my response object into an array like this structure exactly...
var newFilteredStructuredArray = [
{goodProperty1: 'abc'},
{goodProperty2: 'bcd'},
{goodProperty3: 'cde'},
{goodProperty4: 'def'},
{goodProperty5: 'fgh'}
];
However I'd like to filter out the bad properties before I get my new array. I'd like my array to only include these specific property names and filter everything else that I started with.
var possiblePropertyNames = ['goodProperty1', 'goodProperty2', 'goodProperty3', 'goodProperty4', 'goodProperty5'];
an implementation using filter and map on the object entries of response. In the filter stage I filter out only if it is available in possiblePropertyNames. Then in the map stage I return the array in the format you need
var possiblePropertyNames = ['goodProperty1', 'goodProperty2', 'goodProperty3', 'goodProperty4', 'goodProperty5'];
var response = {badProperty1: "bad property text",goodProperty1: "abc",goodProperty2: "bcd",goodProperty3: "cde",goodProperty4: "def",goodProperty5: "efg",badProperty2: "fgh"}
var newFilteredStructuredArray = Object.entries(response).filter(([k,v]) => possiblePropertyNames.includes(k)).map(([k,v]) => ({[k]:v}))
console.log(newFilteredStructuredArray)without es6
var possiblePropertyNames = ['goodProperty1', 'goodProperty2', 'goodProperty3', 'goodProperty4', 'goodProperty5'];
var response = {badProperty1: "bad property text",goodProperty1: "abc",goodProperty2: "bcd",goodProperty3: "cde",goodProperty4: "def",goodProperty5: "efg",badProperty2: "fgh"}
var newFilteredStructuredArray = Object.keys(response)
.filter(function(a){
return possiblePropertyNames.includes(a)
})
.map(function(b){
return {[b]:response[b]}
})
console.log(newFilteredStructuredArray)UPDATE better answer with just a map on the possiblePropertyNames array as pointed out by Andreas in the comments
var possiblePropertyNames = ['goodProperty1', 'goodProperty2', 'goodProperty3', 'goodProperty4', 'goodProperty5'];
var response = {badProperty1: "bad property text",goodProperty1: "abc",goodProperty2: "bcd",goodProperty3: "cde",goodProperty4: "def",goodProperty5: "efg",badProperty2: "fgh"}
var newFilteredStructuredArray = possiblePropertyNames.map(prop => ({[prop]:response[prop]}))
console.log(newFilteredStructuredArray)
