    Initial solution in JS. I will post an optimized solution later.

    function sockMerchant(n, ar){
  
    let pairCount = 0;
    
    while(ar.length>1) {
      for(let i = 1; i < ar.length; i++) {
        if(ar[0] === ar[i]) {
          pairCount += 1
          ar.splice(0, 1)
          ar.splice(i-1, 1)
          i = 0
        }
      }
      ar.splice(0, 1)
    }
    return pairCount

}
