In this article, I'll share 7 optimization tips that every JavaScript developer should know. Use Native JavaScript methods to make your code run faster. Minify your code, use a task runner and use a module bundler. Cache DOM elements in your code to avoid querying the DOM multiple times. Use a framework or library, such as Browserify, Gulp and Grunt, to optimize your code. Use JavaScript's built-in methods more performant than the code you would write yourself.
