try like this.

var test = ["", "A Sample PDF.pdf", " ", "file_example_JPG_100kB.jpg", " "];

var newT = [];

for(var ind = 0; ind < test.length; ind++){
    if((test[ind].trim()).length > 0){
        newT.push(test[ind]);
    }
}

console.log(newT);

You can try something like this:

var test = ["", "A Sample PDF.pdf", " ", "file_example_JPG_100kB.jpg", " "]

var filteredData = test.filter(i => {
  return i.replace(/ /g, "").length > 0
})

console.log(filteredData);
