20 Javascript Tips and Tricks for Writing Better Code
Master the Art of Javascript Programming with These Insider Secrets
- Use descriptive variable names to make your code easier to read and understand.
- Use the “ESLint” tool to enforce a consistent coding style and identify potential errors.
- Make use of JavaScript’s built-in functions and methods to avoid reinventing the wheel.
- Use “arrow functions” to create concise, anonymous functions.
- Avoid using global variables as much as possible.
- Use “try-catch” statements to gracefully handle errors and exceptions in your code.
- Use “template literals” to create multi-line strings and embed expressions within strings.
- Use “destructuring” to easily extract values from objects and arrays.
- Use “spread operator” to expand arrays and objects in function calls and assignments.
- Use “default parameters” to specify default values for function arguments.
- Use “rest parameters” to accept an indefinite number of arguments in a function.
- Use “map”, “filter”, and “reduce” to transform and manipulate arrays more efficiently.
- Use “sets” and “maps” to store and manipulate data efficiently.
- Use “promises” to handle asynchronous operations in a more organized and readable way.
- Use “async-await” to make asynchronous code look and behave like synchronous code.
- Use “classes” to create reusable objects with encapsulated data and methods.
- Use “module exports” and “imports” to organize and reuse code across multiple files.
- Use “webpack” to bundle and optimize your code for the web.
- Use “babel” to transpile modern JavaScript code to run in older browsers.
- Use “Jest” for unit testing and “Enzyme” for testing React components.
