match characters in curly braces regex js


Here is what the above code is Doing:
1. We’re using the re.sub() function to replace all instances of the pattern with the replacement string.
2. The pattern is a regular expression that looks for the pattern {([^}]+)}
3. The replacement string is \1, which means “insert the text of group 1 here”.
4. The regular expression has two groups (within the parentheses). The first group is ([^}]+) which matches one or more characters that are not a close brace. The second group is the close brace.
5. The \1 in the replacement string refers to the first group, which is the text between the braces.
