So I tried to use JSON.stringify(obj) but the load function (which of course isn't empty, this is just for the purpose of this example) is being "lost". Is there any way to stringify and object and maintain the methods it has? Thanks! 回答1: Why exactly do you want to stringify the object? JSON doesn't understand functions (and it's not supposed to).

函数的类型 函数是 JavaScript 中的一等公民 函数声明 在 JavaScript 中，有两种常见的定义函数的方式——函数声明（Function Declaration）和函数表达式（Function Expression）： // 函数声明（Function Declaration） function sum(x, y) { return x + y; } // 函数表达式（Function Expression） let mySum = function (x, y) { return x + y; }; 一个函数有输入和输出，要在 TypeScript 中对其进行约束，需要把输入和输出都考虑到，其中函数声明的类型定义较简单： function sum(x: number, y: number): number { return x + y; } 注意， 输入多余的（或者少于要求的）参数，是不被允许的 ： function sum(x: number, y: number): number { return x + y; } sum(1, 2, 3); // index.ts(4,1): error TS2346: Supplied parameters do not match any signature of call target. function sum(x:
