JavaScript Essentials for Programming with React
summary
Modern JavaScript for React emphasizes concrete edits: replace var with use const not var and prefer let only when mutation is necessary; drop arguments and use rest and spread to handle variable args and to merge arrays/objects; prefer for...of with destructuring and template literals for clearer code; treat arrow functions as lexically binding this/arguments and avoid bind in React; use ES modules with at most one default export and remember classes are syntax over prototypal inheritance.
