Fabio RussoI don't like objects...that much!
This is an object:
const obj = {breed:"labrador",age:9}
But sometimes I prefer to work with arrays.
Why? Because they really look better to me... and there are really a lot of methods or loops that work just with [arrays]!
These are some tools used to "convert" objects to arrays.
//Object.values() will give you an array of all the object "values"
const obj = {breed:"labrador",age:9}
const values = Object.values(obj)
console.log(values)
//-> ["labrador", 9]
//Object.keys() will give you an array of all the object "keys"
const obj = {breed:"labrador",age:9}
const keys = Object.keys(obj)
console.log(keys)
//-> ["breed", "age"]
//Object.entries() will give you an arraysh version of the object.
//Where the key and the value will be paired into an array...
//and all of those arrays will be "pushed" into another array.
const obj = {breed:"labrador",age:9}
const entries = Object.entries(obj)
console.log(entries)
//->[["breed", "labrador"], ["age", 9]]
This is easy peasy stuff, but very often, at the beginning of my journey in JS, objects were very often a problem for me.
If only they had told me before ...
P.S: These tools are ok... if it’s ok to work with arrays instead of objects.
Sometimes you’ve to use objects... because of performance or long term maintenance.
