process.arch屬性是流程模塊的內置應用程序編程接口，用於獲取編譯當前node.js的計算機的CPU體係結構。
用法:
process.arch
返回值：此屬性返回為其編譯當前node.js的操作係統CPU體係結構。可能的值為“ x32”，“ x64”，“ arm”，“ arm64”，“ s390”，“ s390x”，“ mipsel”，“ ia32”，“ mips”，“ ppc”和“ ppc64”。
以下示例說明了Node.js中process.arch屬性的用法：
範例1：
// Node.js program to demonstrate the
// process.arch Property
// Include process module
const process = require('process');
// Printing process.arch property value
console.log(process.arch);輸出：
x64
範例2：
// Node.js program to demonstrate the
// process.arch Property
// Include process module
const process = require('process');
// Printing process.arch property value
switch(process.arch) {
case 'x32':
console.log("32-bit extended systems");
break;
case 'x64':
console.log("64-bit extended systems");
break;
case 'arm':
console.log("32-bit Advanced RISC Machine");
break;
case 'arm64':
console.log("64-bit Advanced RISC Machine");
break;
case 's390':
console.log("31-bit The IBM System/390, the "
+ "third generation of the System/360"
+ " instruction set architecture");
break;
case 's390x':
console.log("64-bit The IBM System/390, the "
+ "third generation of the System/360"
+ " instruction set architecture");
break;
case 'mipsel':
console.log("64-bit Microprocessor without "
+ "Interlocked Pipelined Stages");
break;
case 'mips':
console.log("32-bit Microprocessor without "
+ "Interlocked Pipelined Stages");
break;
case 'ia32':
console.log("32-bit Intel Architecture");
break;
case 'ppc':
console.log("PowerPC Architecture.");
break;
case 'ppc64':
console.log("64-bit PowerPC Architecture.");
break;
default:
colsole.log(" unknown architecture");
}輸出：
64-bit extended systems
注意：上麵的程序將通過使用node filename.js命令。
