object.entries in javascript code example
Example 1: javascript iterate object key values
Object.entries(obj).forEach(([key, value]) => {
console.log(key, value);
});
Example 2: javascript iterate over object keys and values
const object1 = {
a: 'somestring',
b: 42
};
for (let [key, value] of Object.entries(object1)) {
console.log(`${key}: ${value}`);
}
// expected output:
// "a: somestring"
// "b: 42"
// order is not guaranteed
Example 3: javascript object entries
// Object Entries returns object as Array of [key,value] Array
const object1 = {
a: 'somestring',
b: 42
}
Object.entries(object1) // Array(2) [["a", "something"], ["b", 42]]
.forEach(([key, value]) => console.log(`${key}: ${value}`))
// "a: somestring"
// "b: 42"
Example 4: get all keys of object in javascript
myObject = {
"key": "value",
"key2":"value2"
}
Object.keys(myObject);
//console.log(Object.keys(myObject)) = ["key", "key2"]
Example 5: js object entries
var obj = { foo: 'bar', baz: 42 };
console.log(Object.entries(obj)); // [ ['foo', 'bar'], ['baz', 42] ]
// objeto array-like
var obj = { 0: 'a', 1: 'b', 2: 'c' };
console.log(Object.entries(obj)); // [ ['0', 'a'], ['1', 'b'], ['2', 'c'] ]
Object.entries(obj).forEach(([key, value]) => {
console.log(key + ' ' + value); // "a 5", "b 7", "c 9"
});
