Simple solution without using Recursion
function countNumbers(collection) {
let count = 0;
let newArr = collection.flat(Infinity);
for(let i =0;i<newArr.length;i++){
if(typeof newArr[i]==="number"){
count+=1;
}
}
return count;
};

hi bhaiya do you have 30 min in this week would love to book a topmate session regarding a switch .

[trivedi]

const isNumber =(nums )=>{
let count=0
for (let items of nums){
if(typeof(items)=== "number"){
count++;
}
if(Array.isArray(items)){
count+= isNumber(items)
}
}
return count;
}

const res=isNumber(input)
console.log(res)

[manojpathak]

const countNumbers = (arr) => {
return arr.reduce((totalCount, el) => {
if (typeof el === 'number') totalCount++;
else if (Array.isArray(el)) totalCount += countNumbers(el);

return totalCount;
}, 0);
};
