• ruby combining array 1 string 2 answers

how write array in ruby keeping elements of array in same line?

e.g.

a= ["tom", "jerry"] puts 

gives:

tom jerry 

but need have:

tom, jerry 

thank help!

you can use join method on array this.

a= ["tom", "jerry"] puts a.join(", ") 

interestingly, can multiply array string wish separate elements by:

a= ["tom", "jerry"] puts * ", " 

both of above give same output:

tom, jerry
