javascript - 为什么true || 1 === 1/3在JavaScript中返回true(Why does true ||1 === 1/3 returns true in JavaScript)

Question

I know that === operator used to determine whether its both operands are equal and identical or not.(我知道===运算符用于确定其两个操作数是否相等且相同。)

That is to say that if left side operand has 1 then the right side operand must be 1 for returning true .(也就是说，如果左侧操作数为1，则右侧操作数必须为1才能返回true 。) but I don't get why javascript returns true for this calculation.(但我不明白为什么javascript对于此计算返回true。)

true || 1 === 1/3;

//true;

I don't get how this result can be true in javascript.(我不知道如何在javascript中实现此结果。)

Answer 1

The === Operation will never be checked.(===操作将永远不会被检查。)

The statement is true by true .(该声明是真实的true 。)
