I was getting this weird result when I'm trying to construct an array of objects by using for...in loop for a object
const obj = { name: 'John', age: '25' } for (const property in obj) { const obj1 = { prop1: property, prop2: obj[property] } const result = [].push(obj) console.log(result) }[{prop1: 'name', prop2: 'John'}, {prop1: 'age', prop2: '25'}] Could anyone please help?
push returns the new length of the array, which is why you see 1. Move the array initialization out of the loop and log after the loop is finished:
const obj = { name: 'John', age: '25' } const result = [] for (const property in obj) { const obj1 = { prop1: property, prop2: obj[property] } result.push(obj1) } console.log(result)You are pushing to a new Array that is scoped inside of your loop. You really want to do:
const obj = { name: 'John', age: '25' } const results = []; for(let p in obj){ results.push({ prop1: p, prop2: obj[p] }); } console.log(results)
