I have JSON returned from an API like so:
Contacts: [{ GivenName: "Matt", FamilyName:"Berry" }]
To keep this consitent with my code style (camelCase - lower case first letter) I want to transform the array to produce the following:
contacts: [{ givenName: "Matt", familyName:"Berry" }]
Whats the easiest/best way to do this? create a new Contact object and iterate over all the conatacts in the returned array?
I needed a generic method that accepted an array or object. This is what I'm using (I borrowed KyorCode's firstToLower() implementation):
function convertKeysToCamelCase(obj) {
if (!obj || typeof obj !== "object") return null;
if (obj instanceof Array) {
return $.map(obj, function(value) {
return convertKeysToCamelCase(value);
});
}
var newObj = {};
$.each(obj, function(key, value) {
key = key.charAt(0).toLowerCase() + key.slice(1);
newObj[key] = value;
});
return newObj;
};
Example calls:
var contact = { GivenName: "Matt", FamilyName:"Berry" };
console.log(convertKeysToCamelCase(contact));
// logs: Object { givenName="Matt", familyName="Berry"}
console.log(convertKeysToCamelCase([contact]));
// logs: [Object { givenName="Matt", familyName="Berry"}]
console.log(convertKeysToCamelCase("string"));
// logs: null
console.log(contact);
// logs: Object { GivenName="Matt", FamilyName="Berry"}
