What's wrong with this JavaScript Code (Arrays)? -


below code snippet finds out "how many times each element of array repeated". working expected except doesn't give me "ebay repetition count"

var strarr = ["google","ebay","yahoo","google","ebay","facebook","facebook","google"]; var output= {}; strarr.foreach(function(element) {     var count = 0;     try{         while(strarr.indexof(element) !== -1){             strarr.splice(strarr.indexof(element),1);             count++;          }       }catch(e){         console.log(e);     }  output[element] = count; }); console.log(output);

i tried debugging debugger;, figured out second element of array being skipped.

expected output: 

google:3 ebay:2 yahoo:1 facebook:2

actual output: 

google:3 yahoo:1 facebook:2

  • foreach take google index 0:
  • you removed google list including zero
  • foreach moves index 1 has yahoo ebay moved index 0

sorry bad english
