"declared implicitly"是一个编程术语,指的是在代码中没有显式声明变量类型时,编译器会根据上下文自动推断变量类型。例如,在C++中,使用auto关键字可以让编译器根据变量初始化的值自动推断变量类型。

function declared implicitly
In JavaScript, functions can be declared implicitly using function expressions. This means that a function can be defined and assigned to a variable without using the `function` keyword. Here's an example:
```
// Implicitly declaring a function using a function expression
const add = function(a, b) {
return a + b;
};
// Calling the implicitly declared function
console.log(add(2, 3)); // Output: 5
```
In the example above, the function `add` is declared implicitly using a function expression. It is assigned to the variable `add`, which can then be used to call the function.
declared implicitly 警告
"declared implicitly" 警告是编译器在编译代码时发出的一种警告,表示程序员在代码中有一个变量或函数被隐式声明了,但是没有明确地在代码中声明过。这通常是因为程序员在使用变量或函数之前没有在代码中进行声明。这种情况下,编译器会自动创建一个默认的声明,并发出警告。
