Я изучаю генераторную часть Google Blockly (https://developers.google.com/blockly). Я нашел эти коды из кодов генератора.
Генератор - это часть, которая заменяет блоки на фактические программные коды.
/**
* Order of operation ENUMs.

* rators/Operator_Precedence
*/
Blockly.JavaScript.ORDER_ATOMIC = 0; // 0 "" ...
Blockly.JavaScript.ORDER_NEW = 1.1; // new
Blockly.JavaScript.ORDER_MEMBER = 1.2; // . []
Blockly.JavaScript.ORDER_FUNCTION_CALL = 2; // ()
Blockly.JavaScript.ORDER_INCREMENT = 3; // ++
Blockly.JavaScript.ORDER_DECREMENT = 3; // --
Blockly.JavaScript.ORDER_BITWISE_NOT = 4.1; // ~
Blockly.JavaScript.ORDER_UNARY_PLUS = 4.2; // +
Blockly.JavaScript.ORDER_UNARY_NEGATION = 4.3; // -
Blockly.JavaScript.ORDER_LOGICAL_NOT = 4.4; // !
Blockly.JavaScript.ORDER_TYPEOF = 4.5; // typeof
Blockly.JavaScript.ORDER_VOID = 4.6; // void
Blockly.JavaScript.ORDER_DELETE = 4.7; // delete
Blockly.JavaScript.ORDER_AWAIT = 4.8; // await
Blockly.JavaScript.ORDER_EXPONENTIATION = 5.0; // **
Blockly.JavaScript.ORDER_MULTIPLICATION = 5.1; // *
Blockly.JavaScript.ORDER_DIVISION = 5.2; // /
Blockly.JavaScript.ORDER_MODULUS = 5.3; // %
Blockly.JavaScript.ORDER_SUBTRACTION = 6.1; // -
Blockly.JavaScript.ORDER_ADDITION = 6.2; // +
Blockly.JavaScript.ORDER_BITWISE_SHIFT = 7; // << >> >>>
Blockly.JavaScript.ORDER_RELATIONAL = 8; // < <= > >=
Blockly.JavaScript.ORDER_IN = 8; // in
Blockly.JavaScript.ORDER_INSTANCEOF = 8; // instanceof
Blockly.JavaScript.ORDER_EQUALITY = 9; // == != === !==
Blockly.JavaScript.ORDER_BITWISE_AND = 10; // &
Blockly.JavaScript.ORDER_BITWISE_XOR = 11; // ^
Blockly.JavaScript.ORDER_BITWISE_OR = 12; // |
Blockly.JavaScript.ORDER_LOGICAL_AND = 13; // &&
Blockly.JavaScript.ORDER_LOGICAL_OR = 14; // ||
Blockly.JavaScript.ORDER_CONDITIONAL = 15; // ?:
Blockly.JavaScript.ORDER_ASSIGNMENT = 16; // = += -= **= *= /= %= <<= >>= ...
Blockly.JavaScript.ORDER_YIELD = 17; // yield
Blockly.JavaScript.ORDER_COMMA = 18; // ,
Blockly.JavaScript.ORDER_NONE = 99; // (...)
Что на самом деле означают эти коды? Я предполагаю, что это просто операторы, но я хочу знать более конкретно.
