It will match everything in the above list, if the global flag is set.
^/[a-z ]+/ will only match “milk” in the above list.
With regex there is Single-line mode and multiline mode.
Single-line mode is default.
^ and $ do not match at line breaks.
\A and \Z also do not match at line breaks.
Can change the regex to evaluate in multiline mode.
^ and $ will match at the start and end of lines.
\A and \Z does not match at line breaks.
Most Unix tools only support single-line mode.
Multiline came later on.
Most programming languages offer multiline options.
An example of multiline per programming language:
Doing /^[a-z ]+$/ with global and multiline flags on selects all of the following
“milk
“apple juice
“sweet peas”
“sweet peas (2)” –> This will not match
If change /^[a-z ]+$/ to /\A[a-z ]+\Z/ , none of the above match, since we are refencing the entire string, not the beginning and end of a line.
