Class static initialization blocks · V8
Show navigation The new class static initialization block syntax lets developers gather code that should run once for a given class definition and put them in a single place. Consider the following example where a pseudo-random number generator uses a static block to initialize an entropy pool once, when the class MyPRNG definition is evaluated. class MyPRNG { constructor(seed) { if (seed === unde
