I have a reference array based on each English alphabet index:

let reference = [0, 2, 3]; 

and an array of words or even phrases:

let words = ["A", "C", "D"];

And I want to join each word from words array to create a simple sentence but considering the gaps between words ( whenever the values in the reference array aren't consecutive numbers! ), so the desired output would be :

A...C D // gaps filled with three dots

The problem is I can't find a solution to use join() method to do it!

Any help would be appreciated

You can create a new array from words based on the gaps in reference and then join:

let reference = [0, 2, 3];
let words = ["A", "C", "D"];

let res = [];
reference.forEach((n, i) => {
  if (n - reference[i - 1] >= 2) res.push('...', words[i]);
  else res.push(words[i]);

console.log(res.join(' '));

DynamicQueryable.Join (IQueryable, IEnumerable, string, string , A dynamic function to extract the join key from each element of the first perform an inner join of two sequences based on a common key using Dynamic LINQ. Using this library you can do a simple join in the following the way . myContext.TableA.Join(myContext.TableB,'Id','TableAId','outer',null) in the result selector outer and inner are key words to access the result of the join. Using a key with multiple properties and/or selecting a result with multiple properties can be done in the following way

You could reduce the array by checking the delta of the last value and the actual value.

var reference = [0, 2, 3],
    result = reference.reduce((r, v, i, { [i - 1]: last }) =>
        r + (r && (i && v - last > 1 ? '...' : ' ')) + (v + 10).toString(36).toUpperCase(), '');


How Can I Join Two Tables Dynamically At Runtime In Linq To Sql , so my main concern is how can i join the selected table names dynamically .. i tried using System.Linq.Dynamic model of Scott Gu for dynamic  In query expression syntax, a join (Visual C#) or Join (Visual Basic) clause translates to an invocation of Join. In relational database terms, the Join method implements an inner equijoin. 'Inner' means that only elements that have a match in the other sequence are included in the results.

Taken an approach of comparing reference array values each time while iterating on the actual words array:

let reference = [0, 2, 3, 4, 7];

let words = ["A", "C", "D", "E", "H"];
let prev = 0;
let joined = words[prev];
for (let i = 1, l = words.length; i < l; ++i) {
  const diff = reference[i] - reference[prev];
  if (diff > 1) {
    joined += "..." + words[i];
  } else {
    joined += " " + words[i];

  prev = i;

//Since CDE ar continous and AC and EH are not;

Proceedings 1988 VLDB Conference: 14th International Conference on , Hash - Partitioned Join Method Using Dynamic Destaging Strategy Masaya NAKAYAMA Masaru KITSUREGAWA Mikio TAKAGI Institute of Industrial Science​  The join() method The join() method waits for a thread to die. In other words, it causes the currently running threads to stop executing until the thread it joins with completes its task.

C# | Join() Method, String.Join(String, Obj [ ]). This method is used to concatenate the elements of an object array with the help of a separator between each element  The join () method is used to hold the execution of currently running thread until the specified thread is dead (finished execution). In this tutorial we will discuss the purpose and use of join () method with examples. Why we use join () method?

Proceedings of the Fifteenth International Conference on Very , The conventional Hash Join Methods specify the tuple distribution in buckets you use the DHGH Method , the destaging buckets are selected dynamically  Joining is an important operation in queries that target data sources that have no navigable relationships to each other, such as relational database tables. A join of two data sources is the association of objects in one data source with objects that share a common attribute in the other data source.
