This is a question in my last interview and I'm trying to resolve that: in this case, I want to catch values in the nested object and log them into the console.
const obj1 = {
foo: 1,
bar: {
foo1: 2,
bar1: {
foo2: {
foo3: 3,
bar2: 4
},
bar3: 5
}
}
};
// output: [1,2,3,4,5] //
actually, I mean in a professional way. not with this way:
[obj1.foo, obj1.bar.foo1, obj1.bar.bar1.foo2.foo3, obj1.bar.bar1.foo2.bar2, obj1.bar.bar1.bar3]
You can do something like this
const obj1 = {
foo: 1,
bar: {
foo1: 2,
bar1: {
foo2: {
foo3: 3,
bar2: 4
},
bar3: 5
}
}
};
const getValues = (data, values= []) => {
if(typeof data !== 'object'){
return [...values, data]
}
return Object.values(data).flatMap(v => getValues(v, values))
}
console.log(getValues(obj1))You can get specific property like this:
> function nestedObject (nested) {
> for (const key in nested) {
> if (typeof nested[key] === 'object') {
> for (const nesty in nested[key]) {
> console.log(nested[key][nesty]);
> }
> } else {
> console.log(nested[key]);
> }
> } }
> nestedObject(obj1);
