can i use for in to loop over object key 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]);
});
for (let key in obj) {
let value = obj[key];
console.log(key, value);
}
Example 2: loop through object javascript
var p = {
"p1": "value1",
"p2": "value2",
"p3": "value3"
};
for (var key in p) {
if (p.hasOwnProperty(key)) {
console.log(key + " -> " + p[key]);
}
}
for (var key of Object.keys(p)) {
console.log(key + " -> " + p[key])
}
for (let [key, value] of Object.entries(p)) {
console.log(`${key}: ${value}`);
}
