Put command output into string

If I execute some command in a Linux shell, how can I store the output into a string (variable) so I can use it later? I need this for a Bash script, please help.

Just to add to the other answers, you can use the command output directly in another command without assigning it to an intermediate variable. Example:

wget https://feeds.npr.org/510289/podcast.xml -O podcast_`date +%Y-%m-%d`.xml

is short for

TODAY=`date +%Y-%m-%d`
wget https://feeds.npr.org/510289/podcast.xml -O podcast_${TODAY}.xml

and today evaluates to

wget https://feeds.npr.org/510289/podcast.xml -O podcast_2020-11-29.xml

result=`command` or result=$(command) both assign the output of command to the result variable.
