值类型和引用类型区别
值类型和引用类型区别:<script type="text/javascript"> var i = 1; var j = 2; var a = [1, 2]; function arr(b) { b[0] = 2; } function me(x, y) { x = x+y; return x; } arr(a); console.log(i); // 1 console.log(JSON.stringify(a)); // [2,2] </script&g
导读值类型和引用类型区别:<script type="text/javascript"> var i = 1; var j = 2; var a = [1, 2]; function arr(b) { b[0] = 2; } function me(x, y) { x = x+y; return x; } arr(a); console.log(i); // 1 console.log(JSON.stringify(a)); // [2,2] </script&g
<script type="text/javascript">
var i = 1;
var j = 2;
var a = [1, 2];
function arr(b) {
b[0] = 2;
}
function me(x, y) {
x = x+y;
return x;
}
arr(a);
console.log(i); // 1
console.log(JSON.stringify(a)); // [2,2]
