One possible implementation could be:

function mapLimit(inputs, limit, iterateeFn, callback) {
  let index = 0;
  const outputs = [];

  function postCompletionCallback(output) {
    outputs.push(output);
    
    if (outputs.length === inputs.length) {
      callback(outputs);
    }
    
    if (index &gt;= inputs.length) {
      return;
    }
    
    iterateeFn(inputs[index], postCompletionCallback);
    index += 1;
  };
  
  while(index &lt; limit) {
    iterateeFn(inputs[index], postCompletionCallback);
    index += 1;
  }
}
