Find out all about the JavaScript concat() method of a string
Concatenates the current string with the string passed as parameter.
Example:
'Flavio'.concat(' ').concat('Copes') //'Flavio Copes'
You can specify a variable number of arguments, and if you do so all those arguments will be concatenated to the original string:
'Flavio'.concat(' ', 'Copes') //'Flavio Copes'
