Get the element with the highest occurrence in an array

Question

I\'m looking for an elegant way of determining which element has the highest occurrence (mode) in a JavaScript array.

For example, in

[\'pear\', \'a         


        

Answer 1

a=['pear', 'apple', 'orange', 'apple'];
b={};
max='', maxi=0;
for(let k of a) {
  if(b[k]) b[k]++; else b[k]=1;
  if(maxi < b[k]) { max=k; maxi=b[k] }
}
