Answer 1

Sort the array of sentences, and then loop through it and delete an item if it is the same as the previous one:

texts.sort();
for(var i = 1; i < texts.length; i++){
    if(texts[i] === texts[i-1]){
        texts.splice(i,1);
        i--;
     }
}

I tested this in an array with 800 strings, and it seemed reasonably fast.
