Hello Friends 👋,
Welcome to Infinitbility.
Sometime we need get all keys of object, like validating objects details, manage object as daynamics keys and all values.
In this times, we need all keys list whitch we will use to get objects values.
Mostly, we need to maintain daynamic object whitch we don’t how much keys we get.
Now, let’s move to solution, how we get all keys and how to use them for get values from object in javascript.
let assume, we have below example object whitch we will use to get all keys example and use keys example.
let User = {
id: 1,
name: "infinitbility",
slogan: "We have the ability to build infinite way for us.",
dob: "2021-07-26",
isActive: 1
};
Javascript, Get all keys
Javascript provide Object.keys()
method to get all keys in array, Yes it will return array of keys.
let User = {
id: 1,
name: "infinitbility",
slogan: "We have the ability to build infinite way for us.",
dob: "2021-07-26",
isActive: 1
};
let userKeys = Object.keys(User);
console.log("userKeys =>", userKeys);
Output
Javascript, Use retrived keys example
To use keys get using Object.keys()
method, we will use loop of keys and pass each keys in object to get value.
let User = {
id: 1,
name: "infinitbility",
slogan: "We have the ability to build infinite way for us.",
dob: "2021-07-26",
isActive: 1
};
let userKeys = Object.keys(User);
console.log("userKeys =>", userKeys);
for(let key of userKeys){
console.log(key, " => ", User[key]);
}
Output
