JS Join () function converts an array into a string

The join () method is used to put all the elements in an array into a string. The effect is to convert an array to a string, with the same effect as ToString ().

The elements are delimited by the specified delimiter.

For example:

var asp=[' H ', ' ell ', ' o ';
A=asp.join (' # ');  #: Indicates what symbolic link a=asp.join ('); Output: Hello
Console.log (a); Output: H#ell#o

Purpose: Combination of HTML code strings
