如何在两个其他字符串之间获取多个字符串

Question

I am trying to find all values between {{ and }} that start with a $ followed by [\\w.]+ but doesn't start with a number. This works in getting the value, however, it only gets the last item. What I am looking for, is a list of these items, so in this example I would like my array to contain (based off the example):

['{{I\'m $name and I am $age years old}}', '$name', '$age']

When executed, $name is not included in this array as seen here:

 let result = '$welcome: {{I\\'m $name and I am $age years old}}'.match(/\\{\\{.*(\\$(?!\\d|\\.)[\\w.]+).*\\}\\}/) console.log(result)

Answer 1

You could try the below regex:

\$[.\w]+(?=[^{}]*})

This doesn't really match between {{ and }} but it guarantees that it wouldn't find a match which is outside of braces. It assumes that single, unbalanced braces do not occur in input string.

Another approach would be matching an entire {{...}} block then looking for \\$[\\w.]+ but if you need to replace them in original input string this wouldn't be an easy option.
