JavaScript: Return `this` in each method to allow chaining

Method chaining is a popular pattern in JavaScript where you can call multiple methods on the same object consecutively. To allow a class\'s method to be chainable, you need to ensure that each method returns this, which refers to the instance of the class.\n\nHere\'s a step-by-step guide on how to implement method chaining in a class:\n\nStep-by-Step Guide\n- Define a Class: Create a class with some properties and methods.\n- Return this from Methods: Ensure each method returns this to allow chaining.\n\n# Code\n```\nclass Calculator {\n    \n    /** \n     * @param {number} value\n     */\n    constructor(value) {\n        this.result = value;\n    }\n    \n    /** \n     * @param {number} value\n     * @return {Calculator}\n     */\n    add(value){\n        this.result += value;\n        return this\n    }\n    \n    /** \n     * @param {number} value\n     * @return {Calculator}\n     */\n    subtract(value){\n        this.result -= value;\n        return this\n    }\n    \n    /** \n     * @param {number} value\n     * @return {Calculator}\n     */  \n    multiply(value) {\n        this.result *= value;\n       return this\n    }\n    \n    /** \n     * @param {number} value\n     * @return {Calculator}\n     */\n    divide(value) {\n        if(value==0){\n            throw Error("Division by zero is not allowed")\n        }else{\n            this.result /= value;\n            return this\n        }\n    }\n    \n    /** \n     * @param {number} value\n     * @return {Calculator}\n     */\n    power(value) {\n        this.result **= value;\n        return this\n    }\n    \n    /** \n     * @return {number}\n     */\n    getResult() {\n        return this.result;\n    }\n}\n```
