JavaScript Removing empty strings from array removing empty strings from a list in python,removing empty

I understand there are other pages on this but I am trying to get my own working and I do not know why it is not working. I am new to node.js.

for (var index in output)
{
    if (opt.options.showEmpty != true)
    {
        var check = arrayIsEmpty(output[index]);

        if ( check == true )
        {
            continue;
        }
        else
        {
            var array = removingEmptyString(output[index]);

            console.log(index + "\t" + array);
            //console.log(index+ "\t" + output[index]);
        }
    }
}

function removingEmptyString(array)
{
    var newArray;

    for( var i = 0; i < array.length; i++)
    {
        if(array[i] != "" || array[i] != null)
        {
            newArray[i] = array[i];
        }
    }

    return newArray;
}

My result is tree,,, that i was previously getting before the code i wrote. now i get an error of

    newArray[i] = array[i];
                                ^
TypeError: Cannot set property '0' of undefined

You could just use the .filter method in Array's prototype.

var pirate = ['a','1','',0];

function arr (value) {
  return value.filter(function (item) {
    return item !== '';
  });
}

arr(pirate);
// <- ['a','1',0]

As an alternative, you might want to consider naming the callback to .filter

var pirate = ['a','1','',0];

function worthy (value) {
  return value !== '';
}

pirate.filter(worthy);
// <- ['a','1',0]

In the spirit of learning, here is a working version of your solution:

function removingEmptyString(array) {
    'use strict';
    var newArray = [];  // don't forget to initialize it
    for( var i = 0, len = array.length; i < len; i += 1) {
        if(typeof array[i] === 'string' && array[i].length > 0) {
            // add the string to the end of the new array
            newArray.push(array[i]);
        }
    }
    return newArray;
}
