loop object and return value javascript code example
Example 1: javascript loop object
let obj = {
key1: "value1",
key2: "value2",
key3: "value3"
}
Object.keys(obj).forEach(key => {
console.log(key, obj[key]);
});
// key1 value1
// key2 value2
// key3 value3
// using for in - same output as above
for (let key in obj) {
let value = obj[key];
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
