要将一个 JavaScript 对象转换为整数,需要使用 parseInt() 函数。该函数接受两个参数,第一个是要转换的值,第二个是基数(即进制数)。如果未提供第二个参数,则默认为十进制。例如:
```
let obj = { number: "42" };
let num = parseInt(obj.number);
console.log(num); // 42
```
在上面的示例中,我们将一个包含字符串 "42" 的对象转换为整数。首先我们提取对象的 number 属性,然后将其作为参数传递给 parseInt() 函数,最后将返回的整数存储在变量 num 中。

js object转int
如果你想将一个 JavaScript 对象转换为整数值,你可以使用 parseInt() 函数。该函数将一个字符串参数解析为指定进制的整数,所以你需要首先将对象转换成字符串,然后再使用 parseInt() 函数将其转换为整数。例如:
```
var obj = { num: "123" };
var num = parseInt(obj.num);
console.log(num); // 输出 123
```
需要注意的是,如果对象中的属性值不能转换为整数,parseInt() 函数会返回 NaN。
LittleEndian-Int16 node.js
As an AI language model, I cannot create or run codes. However, I can explain what LittleEndian-Int16 is in Node.js.
LittleEndian-Int16 is a data format in Node.js that represents a 16-bit signed integer in little-endian byte order. In little-endian byte order, the least significant byte is stored first, followed by the most significant byte. This is the opposite of big-endian byte order, where the most significant byte is stored first.
Node.js provides a Buffer class that allows you to work with binary data. You can create a new Buffer object and specify the byte order as little-endian by passing the 'le' argument to the constructor. Here's an example:
```
const buffer = Buffer.alloc(2); // create a new buffer with 2 bytes
buffer.writeInt16LE(-1234); // write a little-endian 16-bit integer value of -1234 to the buffer
console.log(buffer); // <Buffer 2e f7>
```
In this example, the value -1234 is stored in the buffer in little-endian byte order as the hex bytes '2e' and 'f7'.
