It depends on what you want   console log  story   name   story    will concatenate the strings together and print that  For me  I use this because it is easier to see what is going on   Using console log  story  name  story   is similar to concatenation however  it seems to run something like this    var text     story   name   story     console log text join          This is pushing all of the items in the array together  separated by a space   join

You can pass multiple args to log   console log  story   name   story

console log takes multiple arguments  so just use   console log  story   name   story      If name is an object or an array then using multiple arguments is better than concatenation  If you concatenate an object or array into a string you simply log the type rather than the content of the variable   But if name is just a primitive type then multiple arguments works the same as concatenation

There are several ways of consoling out the variable within a string   Method 1    console log  story   name   story      Benefit   if name is a JSON object  it will not be printed as  story   object Object   story   Method 2    console log  story     name     story      Method 3  When using ES6 as mentioned above  console log  story   name  story      Benefit  No need of extra   or    Method 4   console log  story  s story  name     Benefit  the string becomes more readable

Both console log  story    name    story   and console log  story   name   story   works just fine as mentioned in earlier answers   I will still suggest of having a habit of console log  story   name   story    because  if trying to print the object contents  like json object  having  story    objectVariable    story  will convert it into string   This will have output like    story   object Object   story    Just a good practice
