问题 I am working out of the 2nd edition of Jon Erickson's "Hacking: The Art of Exploitation" using a VM (virutalbox) to run the LiveCD it came with (Ubuntu 7.04). In section 0x272 "Using the Heap", the author explains the malloc() and free() functions using an example on pages 77-79. The code for the heap_example.c is as follows: #include <stdio.h> #include <stdlib.h> #include <string.h> int main(int argc,char *argv[]){ char *char_ptr; int *int_ptr; int mem_size; if(argc < 2) mem_size = 50; else

问题 In the chromium console I run {} === {} and I get a Syntax error, unexpected '==='. If I however wrap this in parens, like ({} === {}) then I get false , what I'd expect. Is an object literal, in the first position, confused with a code block or something? 回答1: Without a surrounding parenthesis, {} would be considered as an empty code block in javascript. = followed by a code block would be an invalid syntax. That is why you are seeing an error there. If you wrap it inside of a parenthesis
