Writing an array in a file in ruby -

this question has answer here:

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
