javascript - How does Facebook's React JSX transformer work? -


how possible react allows write jsx (xml) within javascript without throwing errors? have been trying wrap head around it, , not quite sure how underlying code accomplishes this.

simple, looks <script type="text/jsx"> tags, parses them, generates corresponding javascript code, , eval's it.

this why jsx inline transformer should used when developing, having parse jsx code decreases performance of web page. when deploying, should convert jsx code js 1 before deploy.

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
