Set的forEach参数

Topic source

认识包还

#1 Created at ... [Delete] [Delete and Lock User]

Set的forEach的第二个参数应该是this本身吧

s.forEach(function(e,i,set){
    console.log(e + ' in ' + i);
    console.log(set);
});

 A in A
 Set {"A", "B", "C"}
 B in B
 Set {"A", "B", "C"}
 C in C
 Set {"A", "B", "C"}

惊鸿一瞥春不回

#2 Created at ... [Delete] [Delete and Lock User]

应该是的。

另一种尝试

#3 Created at ... [Delete] [Delete and Lock User]

Setbu 不是没有索引参数吗？

捣麝成尘拗莲做寸

#4 Created at ... [Delete] [Delete and Lock User]

第二个参数和第一个参数是一样的
