Concatenating strings or string concatenation means joining two or more strings together. In Ruby, we can use the plus
+ operator to do this, or we can use the double less than operator
<<. In this shot, we will use the
str1 << str2
str1: one of the strings you want to concatenate.
str2: the second of the strings you want to concatenate.
The return value is a new string that is a concatenation of the specified strings.
In the code example below, we create strings and use the
<< operator to concatenate them.
# create strings str1 = "Milk: " str2 = "2 litres" str3 = "Eggs: " str4 = "12" # concatenate strings a = str1 << str2 b = str3 << str4 # print returned values puts a puts b
