Can you subscribe this code for me and why the output of this code is 4?

Question

Let arr=[1,3,4,2]
Let count=0
for(let i=0; i<are.lenght; i++){
i==arr[i]
count++
}
console.log(arr)

Answer 1

Arsham Azami hi,
Is this the whole code and exactly how you wrote it?
If so there are some syntaxes errors:
*Don't capitalize --> let not Let.
*are.lenght --> are is not defined,so arr and length not length.
*i==arr[i] --> == is comparator , so it would return a Boolean value, don't you want to use = only to assign arr[i] to i.
Once that fixed, I tried in playground and console.log(arr) output 1,3,4,2.
From my point of view, the only way to have 4 is by console.log(arr[2]), or console.log(arr.length) or if you used i=arr[i] and console.log it inside the for loop it would make sense as on the first loop:
i=0 --> arr[0]=1 --> i become 1
Then i++ so i=2
Then second loop:
i=2 --> arr[2]=4 --> i become 4
Then i++ so i=5
5>arr.length so no third loop.
Apart from that,if it isn't missing some code , I couldn't figure out why it would give 4.

Answer 2

Oh I should have written "=" instead of "=="😑 thank's for your help and effort to find answer
