自定义 JavaScript 的控制台日志

// store the default log method:
const _log = console.log;

// override:
console.log = (...args) => {
    const prefix = `[${new date().tolocalestring()}]`;
    if (typeof args[0] === "string") args[0] = `${prefix} ${args[0]}`
    else args.unshift(prefix);
    _log(...args);
};

// examples:
console.log("test"); // [date time] test
console.log({a: "b"}); // [date time] {a: "b"}
console.log("hello, %s!", "world"); // [date time] hello, world!
console.log("number: %i", 42); // [date time] number: 42
console.log("%cstylized text", 'color: red'); // [date time] stylized text

const log = (...args) => {
    const prefix = `[${new Date().toLocaleString()}]`;
    if (typeof args[0] === "string") args[0] = `${prefix} ${args[0]}`
    else args.unshift(prefix);
    console.log(...args);
};

// Examples:
log("Test"); // [Date Time] Test
log({a: "b"}); // [Date Time] {a: "b"}
log("Hello, %s!", "World"); // [Date Time] Hello, World!
log("Number: %i", 42); // [Date Time] Number: 42
log("%cStylized text", 'color: red'); // [Date Time] Stylized text
