I am looking for the most efficient way to retrieve the max value from the following object (outputted by dev console on Google) - knowing that the maximum value is 1002 but knowing it can dynamically change:
[Red: 1002, Orange: 24, Blue: 301, Pink: 106]
Any suggestions?
That seems to be an Object, not an Array. const max = Math.max(...Object.values(yourObject)) will do it.

So I’m trying to check names through an array and I don’t want to have to use
if (<array name>[0,1,2,3,4,5,6,7])
{ code in here }
depend on what you are trying to do u can use forEach or map
let arr = [1,2,3,4,5,6,7,8,9,10];
arr.forEach((item)=>{
console.log(`${item} is greater than 5 : ${item>5}`)
})

I need to sort this array of strings like in column 1.
Not sure how to tackle this with sort's compare function.
Edit:
Some more info, it should be alphabetical, but grouped.
So first the non 45 en 90 strings then the 45 and then the 90's.
Some background info:
These are parts numbers for hydraulic fittings. The 45 and 90 are degrees.
Any help welcome!
let items = ['X06BJF06', 'X06BJF45S06', 'X06BJF90S06', 'X08BJF08', 'X08BJF45S08', 'X08BJF90S08']
items.sort((a,b) => a.replace(/^(.)\d+(.*)$/, '$1$2').localeCompare(b.replace(/^(.)\d+(.*)$/, '$1$2')));
console.log(items);

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.

As well as how to use java script to manipulate numbers from whole numbers to float and vice versa.
Thank you very much
var myArray = ["I", "need", "your", "code", "to", "help", "you"];
myArray.forEach(function(element) {
console.log(element);
});
console.log(myArray.join(" "));

I was looking for some way to make calculations on values inside array. I know that I can sum the values, sort it or returs max/min. But I am novice and i do not find anything about harder math. I have formula:

(can't attach images yet...)
And I have an array [somex, somey, somex, somey,somex, somey, ....] Is it possible to calculate the thing like that?
you need some logic like this:
int current=0 ,previous=0,yoursum=0;
for(i=0;i<no. of elements in array;i++)
{
current=arr[i];
else
{
yoursum+=previous-current;
previous=current;
}
}
