"Notes" JavaScript Coding specification-type Assignment & coercion

Executes a coercion type conversion statement.

String

Bad <p>//= This.reviewscore = 9;</p>var a= this.reviewscore + ';//Goodvar Totalscore = ' + This.rev iewscore;//Badvar totalscore = "+ This.reviewscore + ' total score ';//Goodvar Totalscore = this.reviewscore + ' Total Score ';

use parseint to convert numbers and take a binary as a parameter

var a= ' 4 ';//Badvar val = new number (a);//Badvar val = +a;//Badvar val = a>> 0;//Badvar val = parseint (a);//Goo DVar val = number (a);//Goodvar val = parseint (A, 10);

for whatever reason, perhaps you have done something "rude", perhaps parseint has become your bottleneck, perhaps considering performance and the need to use bit arithmetic, use annotations to explain why you did it.

good/*** parseint was the reason my code is slow.* bitshifting the String to coerce it to a * number made it a lot fast Er.*/var val = inputvalue >> 0;

NOTE: When bitwise operations are used, numbers is treated as a 64-bit value, but the bitwise operation always returns a 32-bit integer (source). A bitwise operation with an integer value greater than 32 bits will result in unpredictable behavior. Discussion. The largest signed 32-bit integer is 2,147,483,647

2147483647 >> 0//=> 21474836472147483648 >> 0//=> -21474836482147483649 >> 0//=> 2147483647

Booleans:

var = 0;//Badvar hasage = new Boolean (age);//Goodvar Hasage = Boolean (age);//Goodvar Hasage =!! Age
