node . js process . through defensation Property
原文:https://www . geeksforgeeks . org/node-js-process-throwdeprivation-property/
process . throw-defense 属性是流程模块的内置应用编程接口，用于指示当前 Node.js 流程是否设置了–throw-defense 标志。process.throwDeprecation 是可变的，因此在运行时，是否会因为拒绝警告而导致错误可能会改变。
语法:
process.throwDeprecation
返回值:该属性表示当前 Node.js 进程是否设置了–throw-defense 标志。
下面的例子说明了在 Node.js 中进程的使用。
例 1:
Javascript
// Node.js program to demonstrate the
// process.throwDeprecation Property
// Include process module
const process = require('process');
// Printing process.throwDeprecation
// property value
console.log(process.throwDeprecation);
运行命令:节点–抛出-弃用 hello.js
输出 1:
true
运行命令:节点 hello.js
输出 2:
undefined
例二:
Javascript
// Node.js program to demonstrate the
// process.throwDeprecation Property
// Include process module
const process = require('process');
// Instance Properties
process.throwDeprecation = false;
// Printing process.throwDeprecation
// property value
console.log(process.throwDeprecation);
// Instance Properties
process.throwDeprecation = true;
// Printing process.throwDeprecation
// property value
console.log(process.throwDeprecation);
运行命令:节点–抛出-弃用 hello.js
输出 1:
true
true
运行命令:节点 hello.js
输出 2:
false
true
