+### Normal characters
+
+Expression | Description
+:--|:--
+`.` or `[^\n\r]` | any character *excluding* a newline or carriage return
+`[A-Za-z]` | alphabet
+`[a-z]` | lowercase alphabet
+`[A-Z]` | uppercase alphabet
+`\d` or `[0-9]` | digit
+`\D` or `[^0-9]` | non-digit
+`_` | underscore
+`\w` or `[A-Za-z0-9_]` | alphabet, digit or underscore
+`\W` or `[^A-Za-z0-9_]` | inverse of `\w`
+`\S` | inverse of `\s`
+
+### Whitespace characters
+
+Expression | Description
+:--|:--
+` ` | space
+`\t` | tab
+`\n` | newline
+`\r` | carriage return
+`\s` | space, tab, newline or carriage return
+
+### Character set
+
+Expression | Description
+:--|:--
+`[xyz]` | either `x`, `y` or `z`
+`[^xyz]` | neither `x`, `y` nor `z`
+`[1-3]` | either `1`, `2` or `3`
+`[^1-3]` | neither `1`, `2` nor `3`
+
+- Think of a character set as an `OR` operation on the single characters that are enclosed between the square brackets.
+- Use `^` after the opening `[` to “negate” the character set.
+- Within a character set, `.` means a literal period.
+
+### Characters that require escaping
+
+#### Outside a character set
+
+Expression | Description
+:--|:--
+`\.` | period
+`\^` | caret
+`\$` | dollar sign
+`\|` | pipe
+`\\` | back slash
+`\/` | forward slash
+`\(` | opening bracket
+`\)` | closing bracket
+`\[` | opening square bracket
+`\]` | closing square bracket
+`\{` | opening curly bracket
+`\}` | closing curly bracket
+
+#### Inside a character set
+
+Expression | Description
+:--|:--
+`\\` | back slash
+`\]` | closing square bracket
+
+- A `^` must be escaped only if it occurs immediately after the opening `[` of the character set.
+- A `-` must be escaped only if it occurs between two alphabets or two digits.
+
+### Quantifiers
+
+Expression | Description
+:--|:--
+`{2}` | exactly 2
+`{2,}` | at least 2
+`{2,7}` | at least 2 but no more than 7
+`*` | 0 or more
+`+` | 1 or more
+`?` | exactly 0 or 1
+
+- The quantifier goes *after* the expression to be quantified.
+
+### Boundaries
+
+Expression | Description
+:--|:--
+`^` | start of string
+`$` | end of string
+`\b` | word boundary
+
+- How word boundary matching works:
+    - At the beginning of the string if the first character is `\w`.
+    - Between two adjacent characters within the string, if the first character is `\w` and the second character is `\W`.
+    - At the end of the string if the last character is `\w`.
+
+### Matching
+
+Expression | Description
+:--|:--
+`foo\|bar` | match either `foo` or `bar`
+`foo(?=bar)` | match `foo` if it’s before `bar`
+`foo(?!bar)` | match `foo` if it’s *not* before `bar`
+`(?<=bar)foo` | match `foo` if it’s after `bar`
+`(?<!bar)foo` | match `foo` if it’s *not* after `bar`
+
+### Grouping and capturing
+
+Expression | Description
+:--|:--
+`(foo)` | capturing group; match and capture `foo`
+`(?:foo)` | non-capturing group; match `foo` but *without* capturing `foo`
+`(foo)bar\1` | `\1` is a backreference to the 1st capturing group; match `foobarfoo`
+
+- Capturing groups are only relevant in the following methods:
+    - `string.match(regexp)`
+    - `string.matchAll(regexp)`
+    - `string.replace(regexp, callback)`
+- `\N` is a backreference to the `Nth` capturing group. Capturing groups are numbered starting from 1.
+
