if (a != b) { ("a and b are not equal");} ```在这个例子中，因为`a`是字符串，`b`是数字，所以它们会被转换为数字进行比较。因此，这个if语句会输出"a and b are not equal"。2. `!==`：`!==`在比较之前不会尝试转换操作数的类型。如果两个操作数的类型不同，即使它们的值在转换后相等，`!==
如果相等则断言通过，否则抛出 【AssertionError】3.1 assert.equal(actual, expected[, message])assert.equal()用于测试期望值和实际值是否相等，【在值类型的时候比较的是两个值是否相等，当预期值和实际值为引用类型的时候，比较的是值得引用】

Scavenge is a very fast garbage collection technique and operates with objects inNew Space. Scavenge is the implementation ofCheney’s Algorithm. The idea is very simple,New Spaceis divided in two equal semi-spaces: To-Space and From-Space. Scavenge GC occurs when To-Space is full. It simpl...
