I am working with the following code snippet:
const searchValue = 'XYZ';
const FIELD_MAP = {
'key1': [
'SOME',
'THING'
],
'key2': [
'ANOTHER_VALUE',
'XYZ'
]
};
My goal is to determine which array (key1, key2, etc) contains the value stored in the searchValue variable. What would be the most efficient approach to accomplish this task?
To accomplish this task, we can loop through the properties of FIELD_MAP and verify if the desired search term exists in any of them:
for (var item in FIELD_MAP) {
if (FIELD_MAP.hasOwnProperty(item)) {
if (FIELD_MAP[item].includes(search_value)) {
console.log("Located in =", item)
}
}
}
To achieve this, you can filter the keys in the FIELD_MAP object by checking if the value includes the search_value. This can be done using Object.keys to retrieve the keys and Array.filter to filter them accordingly.
var result = Object.keys(FIELD_MAP).filter(function(key){
return FIELD_MAP[key].includes(search_value);
})[0]; // Omit [0] if you want multiple keys that match the given criteria
