Im working on a Auth flow. A private project for me and some friends
My code is getting raw from A website then its put it into a vatiable.
An example of what is inside the variable
{
"token": "mytoken",
"id": "testid"
}
I would like to get the value of token and print it
let raw = {
"token": "mytoken",
"id": "testid"
}
Then raw.token or raw["token"] should do the trick.

I want to make subfunction like a.b.c(), I can't find name for this. Sorry for english.
What you are describing is just a function within an object, within another object, like so:
const a = {
b: {
c: () => "hello World",
},
};

I have this declared in my class:
somePair: KVPair;
Where KVPair is just a key value pair JSON.
Then in my displayFN I set it like so:
displayFn(pair: KVPair) {
this.somePair = pair;
}
But when I console.log(somePair) outside of displayFn, it's undefined, and I'm not sure why.
I was trying to set it with a [displayWith] which was clearing somePair.
When I set it in (optionSelected)="someFunction($event.option.value)", the value stuck around.

How to Display each variable of for loop in a div tag using javascript? Using innerHTML i am only able to display the last variable of for loop
You can do as follows, but it is better to use lists.
Lists: https://developer.mozilla.org/pt-BR/docs/Web/HTML/Element/ul
const myDreams = ["Fly", "Be rich", "Go to the moon"];
const myDreamsDiv = document.querySelector("#myDreams");
//The secret here is to add a breakline(<br>) between each word.
myDreams.forEach(dream => myDreamsDiv.innerHTML += (dream + "<br>"));
<div id="myDreams"></div>

I have a function that will take in a JSON object which has a similar structure as follows:-
{
"listing": [
{
"rental_prices": {
"shared_occupancy": "N",
"per_week": 2308,
"accurate": "per_month",
"per_month": 10000
},
"country_code": "gb",
"num_floors": "0",
}
]
}
I want to be able to get all the values for per_month from each sub object of listing I can pull a specific one, i.e. using data.listing[0].rental_prices.per_month but I want to be able to iterate over the object and get the value and push it to a new array each time it comes aross the per_month key
Indeed as #mwilson suggested .map would do the trick in this case.
https://repl.it/repls/TriangularModestNormalform
testJson.listing.map(listing => listing.rental_prices.per_month);
Note: This will return an array with undefined items if per_month doesn't exist, and will also crash if renal_prices doesn't exist
