Restaurants A promise in JavaScript is just a pending task. It’s like ordering food at a restaurant: when you place your order, the server makes a promise to bring the food you ordered. Once the food is brought to the table the promise has been fulfilled. If the food you ordered can’t be served because the kitchen is out of a key ingredient, then you can catch a meal somewhere else.

In modern web development, maintaining compatiablity across different browsers and environments is a crucial challenge. Two important tools that help developers overcome this issue are transpilers and polyfills. Both serve the purpose of making code work across different platforms, they operate in distinct ways. What is Transpilers A transpiler is a tool that converts code written in one language ot syntax to another language or syntax. Specially, in the context of Javascript, transpilers convert modern Javascript (ES6+) into older versions of Javascript (like ES5) that can be understood by older browsers on environments. key points: - Syntax-Level Conversion: A transpiler…
