In JavaScript, which of the following method is used to evaluate the regular expression? Select one: a. eval(2*(3+5)) b. evaluate (2*(3+5)) c. evaluate (2*(3+5)) code example

Example: eval

Just use eval command for running string output. As for example:
eval $cmd   #execute command included in string value of $cmd variable
Or for a more sophisticated use run commands stored in lines of a file:
cat commands_file.txt | while read line; do eval $line; done
