seems to work fine Currently I have two arrays , You can loop over the code array:
{% for c in code %}
  {# ... #}
{% endfor %}
{# ... #}
{% if airport == c %}
  {# ... #}
{% endif %}
{# ... #}
{# ... #}
{% set airport = city[loop.index0] %}
{# ... #}
{% for c in code %}
  {% if airport == c %}
    {% set airport = city[loop. index0] %}
  {% endif %}
{% endfor %}
{% set codes = ['AMS', 'EIN', 'RTM'] %} 
{% for code in codes %}
  {{ code }}
{% endfor %}

{# and #}

{% set cities = ['Amsterdam', 'Eindhoven', 'Rotterdam'] %} 
{% for city in cities %}
  {{ city }}
{% endfor %}

How to find index deep in javascript array and return other part of array?

I wish did fix the issue. If you need to find many objects, you can build a lookup table. Iterate over your collection of main objects, and store them in an key-value-map (simple object) by their identifier:
var mainsByKid = {}; // if the keys are integers (and not sparse), use an array
for (var i=0; i<mains.length; i++) {
     var main = mains[i],
         key = main.properties.kid; // must be unique
     mainsByKid[key] = main;
}
mainsByKid[1];

How to find every occurrence of a target value in array and return a new array containing the indexes for these values?

will be helpful for those in need You are never incrementing indexNum, it always remains at 0 and the array keeps on writing the values at this same index.
I think you should have this expression there:
newArray[indexNum++] = i;

PHP: Find string in Multi-dimensional array or return empty array keys?

will be helpful for those in need Your JOIN to the empty beds query is leaving out empty values. I suggest you use a subquery to generate a complete list of room_category values.
            select distinct room_category
              from room_category
select a.room_category, 
       group_concat(b.room_name ORDER BY b.room_name) vacancies
  from (select distinct id, room_category from room_category) a
  left join 
       (select rct.room_category AS room_category,
               rn.room_name 
          from room_category rct  
          left join room_name rn on rn.room_category = rct.id
          left join patient_detail pd on rn.id = pd.bed_type
                 and (isnull(pd.discharge_date) or now() 
                      between pd.admission_date and pd.discharge_date)
         where isnull(pd.id) 
         order by rct.room_category, rn.room_name
    ) b on a.room_category=b.room_category
group by a.room_category
order by a.room_category

Find duplicate objects in array and return new array of object with number of duplicates as a new property

it fixes the issue I think you'd be best suited by creating a helper object. A helper object will initially be empty, but will become populated slowly by what you're reading through. I'm going to assume that the keys in your array are consistent.
const keys = ["Name","Type"]
var counterObj = {}
let keyForCounterObj
arrayOfObjects.forEach((obj)=>{
    keyForCounterObj = ''
    keys.forEach((key)=>{
        keyForCounterObj += String(obj[key])
}
if(counterObj[keyForCounterObj]){
    counterObj[keyForCounterObj].times ++
}else{
    counterObj[keyForCounterObj] = {
        ...obj,
        times:1
}}}
counterObj = {
    AppleFruit: {
        Name:"Apple",
        Type:"Fruit",
        times:3,
    },
    CarrotVegetable:{
        Name:"Carrot",
        Type:"Vegetable",
        times:4,
    }
}
let newArrayOfObjects = []
const counterObjKeys = Object.keys(counterObj)
counterObjKeys.forEach((key)=>{
    newArrayOfObjects.push(counterObj[key])
}
