Number.isSafeInteger() - JavaScript
a safe integer is an integer that can be exactly represented as an ieee-754 double precision number, and whose ieee-754 representation cannot be the result of rounding any other integer to fit the ieee-754 representation.
... for example, 253 - 1 is a safe integer: it can be exactly represented, and no other integer rounds to it under any ieee-754 rounding mode.
... in contrast, 253 is not a safe integer: it can be exactly represented in ieee-754, but the integer 253 + 1 can't be directly represented in ieee-754 but instead rounds to 253 under round-to-nearest and round-to-zero rounding.
... the safe integers consist of all integers from -(253 - 1) inclusive to 253 - 1 inclusive (± 9007199254740991 or ± 9,007,199,254,740,991).

Number.MAX_SAFE_INTEGER - JavaScript

... the reasoning behind that number is that javascript uses double-precision floating-point format numbers as specified in ieee 754 and can only safely represent numbers between -(253 - 1) and 253 - 1.

Preferences - Archive of obsolete content
as of firefox 54, you can pass a default value as the second argument to any get*pref method.
...so you could use, for instance: alert(prefs.getcharpref("mypref", "no value stored")); be careful with this technique because prior to firefox 54, the additional (default) value will be ignored and an exception would still be thrown in this case.

JavaScript data types and data structures - JavaScript
the number type is a double-precision 64-bit binary format ieee 754 value (numbers between -(253 − 1) and 253 − 1).
... this example demonstrates, where incrementing the number.max_safe_integer returns the expected result: > const x = 2n ** 53n; 9007199254740992n > const y = x + 1n; 9007199254740993n you can use the operators +, *, -, **, and % with bigints—just like with numbers.

Numbers and dates - JavaScript
numbers in javascript, numbers are implemented in double-precision 64-bit binary format ieee 754 (i.e., a number between ±2−1022 and ±2+1023, or about ±10−308 to ±10+308, with a numeric precision of 53 bits).

DataView.prototype.setBigInt64() - JavaScript

hat when coerced to numeric type result in a valid non-nan numeric value (notably the empty string and boolean primitives, which when coerced give numeric values zero or one), the "false" returned value may be unexpected; the empty string, for example, is surely "not a number." the confusion stems from the fact that the term, "not a number", has a specific meaning for numbers represented as ieee-754 floating-point values.
... the function should be interpreted as answering the question, "is this value, when coerced to a numeric value, an ieee-754 'not a number' value?" ecmascript 2015 contains the number.isnan() function.

Save-Data - HTTP
note: disabling http/2 server push (rfc 7540, section 8.2: server push) might be desirable too for reducing data downloads.

X-Frame-Options - HTTP
the spec leaves it up to browser vendors to decide whether this option applies to the top level, the parent, or the whole chain, although it is argued that the option is not very useful unless all ancestors are also in the same origin (see bug 725490).

HTTP headers - HTTP
accept-ch-lifetime servers can ask the client to remember the set of client hints that the server supports for a specified period of time, to enable delivery of client hints on subsequent requests to the server’s origin ([rfc6454]).

A re-introduction to JavaScript (JS tutorial) - JavaScript
numbers numbers in javascript are "double-precision 64-bit format ieee 754 values", according to the spec — there's no such thing as an integer in javascript (except bigint), so you have to be a little careful.

Equality comparisons and sameness - JavaScript
briefly: double equals (==) will perform a type conversion when comparing two things, and will handle nan, -0, and +0 specially to conform to ieee 754 (so nan != nan, and -0 == +0); triple equals (===) will do the same comparison as double equals (including the special handling for nan, -0, and +0) but without type conversion; if the types differ, false is returned.

Grammar and types - JavaScript
