Some are watching the sunset, while others patiently wait for thunderstorms to roll in. Many are simply laughing around the fire with friends, reminiscing about years of epic escapes and sharing plans for ones still to come.
According to ECMA-262, on the one hand, regular expression "syntax characters" are always non-alphanumeric, such that the result is secure, and special escape sequences (\d, \w, \n) are always alphanumeric such that no false control escapes will be produced.
In the GitHub && NPM page are descriptions of how to use the shim/polyfill for this option, as well. That logic is based on return RegExp.escape implementation;, where implementation contains the regexp used above.
Just published a regex escape gist based on the RegExp.escape shim which was in turn based on the rejected RegExp.escape proposal. Looks roughly equivalent to the accepted answer except it doesn't escape - characters, which seems to be actually fine according to my manual testing.
Note: escape() is a non-standard function implemented by browsers and was only standardized for cross-engine compatibility. It is not required to be implemented by all JavaScript engines and may not work everywhere. Use encodeURIComponent() or encodeURI() if possible.
Note: This function was used mostly for URL encoding and is partly based on the escape format in RFC 1738. The escape format is not an escape sequence in string literals. You can replace %XX with \xXX and %uXXXX with \uXXXX to get a string containing actual string-literal escape sequences.

In computing and telecommunication, an escape character is a character that invokes an alternative interpretation on the following characters in a character sequence. An escape character is a particular case of metacharacters. Generally, the judgement of whether something is an escape character or not depends on the context.
In the telecommunications field, escape characters are used to indicate that the following characters are encoded differently. This is used to alter control characters that would otherwise be noticed and acted on by the underlying telecommunications hardware, such as illegal characters. In this context, the use of escape characters is often referred to as quoting.
Escape characters are part of the syntax for many programming languages, data formats, and communication protocols. For a given alphabet an escape character's purpose is to start character sequences (so named escape sequences), which have to be interpreted differently from the same characters occurring without the prefixed escape character.
Generally, an escape character is not a particular case of (device) control characters, nor vice versa. If we define control characters as non-graphic, or as having a special meaning for an output device (e.g. printer or text terminal) then any escape character for this device is a control one. But escape characters used in programming (such as the backslash, "\") are graphic, hence are not control characters. Conversely most (but not all) of the ASCII "control characters" have some control function in isolation, therefore they are not escape characters.
The ASCII "escape" character (octal: \033, hexadecimal: \x1B, or, in decimal, 27, also represented by the sequences ^[ or \e) is used in many output devices to start a series of characters called a control sequence or escape sequence. Typically, the escape character was sent first in such a sequence to alert the device that the following characters were to be interpreted as a control sequence rather than as plain characters, then one or more characters would follow to specify some detailed action, after which the device would go back to interpreting characters normally. For example, the sequence of ^[, followed by the printable characters [2;10H, would cause a Digital Equipment Corporation (DEC) VT102 terminal to move its cursor to the 10th cell of the 2nd line of the screen. This was later developed into ANSI escape codes covered by the ANSI X3.64 standard. The escape character also starts each command sequence in the Hewlett-Packard Printer Command Language.
Many modern programming languages specify the double-quote character (") as a delimiter for a string literal. The backslash (\) escape character typically provides two ways to include double-quotes inside a string literal, either by modifying the meaning of the double-quote character embedded in the string (\" becomes "), or by modifying the meaning of a sequence of characters including the hexadecimal value of a double-quote character (\x22 becomes ").
C, C++, Java, and Ruby all allow exactly the same two backslash escape styles. The PostScript language and Microsoft Rich Text Format also use backslash escapes. The quoted-printable encoding uses the equals sign as an escape character.
URL and URI use %-escapes to quote characters with a special meaning, as for non-ASCII characters. The ampersand (&) character may be considered as an escape character in SGML and derived formats such as HTML and XML.
The Point-to-Point Protocol (PPP) uses the 0x7D octet (\175, or ASCII: }) as an escape character. The octet immediately following should be XORed by 0x20 before being passed to a higher level protocol. This is applied to both 0x7D itself and the control character 0x7E (which is used in PPP to mark the beginning and end of a frame) when those octets need to be transmitted by a higher level protocol encapsulated by PPP, as well as other octets negotiated when the link is established. That is, when a higher level protocol wishes to transmit 0x7D, it is transmitted as the sequence 0x7D 0x5D, and 0x7E is transmitted as 0x7D 0x5E.
In Bourne shell (sh), the asterisk (*) and question mark (?) characters are wildcard characters expanded via globbing. Without a preceding escape character, an * will expand to the names of all files in the working directory that do not start with a period if and only if there are such files, otherwise * remains unexpanded. So to refer to a file literally called "*", the shell must be told not to interpret it in this way, by preceding it with a backslash (\). This modifies the interpretation of the asterisk (*). Compare:
The Windows command-line interpreter uses a caret character (^) to escape reserved characters that have special meanings (in particular: &, , (, ), , ^).[4] The DOS command-line interpreter, though it has similar syntax, does not support this.
Accelerated cellular senescence (ACS) has been described for tumor cells treated with chemotherapy and radiation. Following exposure to genotoxins, tumor cells undergo terminal growth arrest and adopt morphologic and marker features suggestive of cellular senescence. ACS is elicited by a variety of chemotherapeutic agents in the p53-null, p16-deficient human non-small cell H1299 carcinoma cells. After 10 to 21 days, infrequent ACS cells (1 in 10(6)) can bypass replicative arrest and reenter cell cycle. These cells express senescence markers and resemble the parental cells in their transcription profile. We show that these escaped H1299 cells overexpress the cyclin-dependent kinase Cdc2/Cdk1. The escape from ACS can be disrupted by Cdc2/Cdk1 kinase inhibitors or by knockdown of Cdc2/Cdk1 with small interfering RNA and can be promoted by expression of exogenous Cdc2/Cdk1. We also present evidence that ACS occurs in vivo in human lung cancer following induction chemotherapy. Viable tumors following chemotherapy also overexpress Cdc2/Cdk1. We propose that ACS is a mechanism of in vivo tumor response and that mechanisms aberrantly up-regulate Cdc2/Cdk1 promotes escape from the senescence pathway may be involved in a subset of tumors and likely accounts for tumor recurrence/progression.
A 27-hour experience, this overnight retreat is designed as an escape from the Hilltop. Enjoy the chance to meet awesome new people, eat lots of good food, listen to live music, play games, and take a step back from the frenzy of campus life. ESCAPE is accessible to people of all religious and non-religious backgrounds
Registration is $40.00 and covers the cost of the overnight stay, meals, an ESCAPE t-shirt, and other fun ESCAPE swag. Registration fees are non-refundable. If the fee poses a challenge, financial assistance is available. Please email esc...@georgetown.edu for more information.
How much does it cost?
We charge a flat rate of $149. This is for a group of up to five people in on-site rooms at the time your reservation is arranged. Rooms that support more than five people are $29 per additional person up the maximum capacity for that room. Each escape room experience is private to your group.
What if I am not a Kroc Center member?
Everyone is welcome to use the escape rooms, members and non-members. If you win, your team earns a day for each player to enjoy the amenities at the Kroc.
How long does it take?
The actual to escape the room is a 60 minute countdown. Plan on a few minutes before the session for orientation, and a few minutes afterwards for celebration and selfies.
Where are you located?
The Kroc escape rooms are in the Salem Kroc Center. Check in with your group at the Front Desk a few minutes ahead of your appointment. The Kroc Center is in North Salem off of Portland Road. The address is 1865 Bill Frey Drive, Salem, OR 97301.
