constexpr specifier (since C++11) -
Conditional execution statements. Iteration statements (loops). Jump statements. Functions. Function declaration. Lambda function declaration. inline specifier. Exception specifications (until C++20). noexcept specifier (C++11). Exceptions. Namespaces. Types. Specifiers. Storage duration specifiers.
Understanding constexpr specifier in C++ - GeeksforGeeks
constexpr is a feature added in C++ 11. constexpr specifies that the value of an object or a function can be evaluated at compile time and the expression can be used in other constant expressions.
constexpr Functions -
constexpr functions are functions that can be executed at compile time. Sounds not so thrilling. But it is. Trust me. You can perform with constexpr functions a lot of calculations at compile time.

4.14 — Const, constexpr, and symbolic constants | Learn C++
constexpr variables are const. This will get important when we talk about other effects of const in upcoming lessons. A better way to create symbolic constants is through use of constexpr variables
C++ - constexpr functions | c++ Tutorial
C++ constexpr functions. Example. A function that is declared constexpr is implicitly inline and calls to such a function potentially yield constant expressions.
constexpr` is a Platform
Let me share a useful insight with you: constexpr is a platform. Just like you write code that targets Windows or a microcontroller, you write code that targets compile-time execution.
Constexpr Additions in C++17 - Simplify C++!
constexpr closure object constexpr auto add5 = adder(5) However with the old if, the other branch still had to compile. With if constexpr that is no longer the case, the compiler will no longer attempt that.
constexpr if - 7 Features of C++17 that will simplify your code
Hmm... constexpr if can be used to replace several tricks that were already done So, in most of the cases, we can now just write a constexpr if statement and that will yield much cleaner code.
Constexpr constructors (C++11)
Constexpr constructors (C++11). Note: IBM supports selected features of C++11, known as C++0x before its ratification. IBM will continue to develop and implement the features of this standard.

Asserts in constexpr functions. Posted on May 18, 2017 by Andrzej Krzemieński. Assertions (like C-style macro assert) are not an ideal, but still useful tool for indicating assumptions about program...
constexpr allows reinterpret_cast in function body
For example, the constexpr function that has a reinterpret_cast in it, have you used it "Warning, non constant expression used in function <f> marked as constexpr. This is ill formed if used as a constant...

The Missing for constexpr
With C++17 we finally get if constexpr. However, I have started running into a lot of cases where I want a for constexpr that is guaranteed to be evaluated at compile time.
