I made a recipe box with ReactJS. Please let me know what room for improvement you see. I did notice that with codepen, the list of components started to become lengthy to look at. Is it a best practice to separate the different components into different js files? Here is the codepen: https://codepen.io/capozzic1/pen/gmpVyr. Here is the code:
var Grid = ReactBootstrap.Grid;
var Col = ReactBootstrap.Col;
var Row = ReactBootstrap.Row;
/*
Component ideas
-recipeCon
-RecipeList
-Recipe ingredients
-edit-delete
-addRecipe button
-recipe entry
*/
var recipes = [{
title: "Pizza",
ingredients: ["Tomato Sauce", "Yeast"]
}, {
title: "Cookies",
ingredients: ["Cookie Dough", "Chocolate chips"]
}, {
title: "Turkey tacos",
ingredients: ["Nacho cheese taco shells", "Turkey"]
}
]
//holds all other components. has add/edit methods
