If I have a list of strings, how can I search for all values in a key-value object using my list of strings, and then return the corresponding keys?
"listOfStrings": ["4444", "5555"]
"secretCodes": [
{
"secret": "John",
"value": "4444"
},
{
"secret": "Paul",
"value": "0001"
},
{
"secret": "George",
"value": "0002"
},
{
"secret": "Ringo",
"value": "5555"
},
{
"secret": "Pete",
"value": "0008"
}
]
If you're looking to retrieve the secret aliases that correspond with the codes given in the array, you can achieve it using the following method:
let secretCodes = [
{ secret: "John", value: "4444" },
{ secret: "Paul", value: "0001" },
{ secret: "George", value: "0002" },
{ secret: "Ringo", value: "5555" },
{ secret: "Pete", value: "0008" },
];
function getSecretName(codes) {
let matchingValues = secretCodes.filter(obj => codes.includes(obj.value));
return matchingValues.map(value => value.secret);
}
console.log(getSecretName(["4444", "5555"]));
// Output: ["John", "Ringo"]Iterate over the elements and save them in a designated variable.
const classifiedItems = [];
confidentialData.forEach(element => {
if (Sensitive.includes(element.value)) {
classifiedItems.push(element)
}
})
To effectively handle data of this nature, utilizing the Array prototype functions is recommended.
filter works well when you need an array that contains a specific subset of the datamap is ideal for transforming each element into a new onesome is most suitable when determining if any element in the array matches your criteriaSecurityCodes = ["4444", "5555"]
secretCodes = [
{"secret": "John", "value": "4444"},
{"secret": "Paul", "value": "0001"},
{"secret": "George", "value": "0002"},
{"secret": "Ringo", "value": "5555"},
{"secret": "Pete", "value": "0008"}
]
const validCodes = secretCodes.filter(code => SecurityCodes.some( el => el === code.value))
console.log(validCodes)
const approvedSecrets = validCodes.map(code => code.secret)
console.log(approvedSecrets)When you assign the variables `secretCodes` and `codes`, you can use this code snippet:
secretCodes.forEach(item =>{
codes.forEach(code =>{
if (item['value'] === code){
console.log(item['secret'])
}
})
})
