Ternary operators

Question

I need a ternary operator here but not sure of the structure. Or is best practice is to add inside of map? I'm confused of how this works

{this.state.recipes.map((recipe, id) =>{
return (
<div>
Hi
</div>
)}

Answer 2

What is the condition you wish to set from your ternary operator?

Answer 3

Normally we run map first then filter it using ternary operator in its callback.

Answer 4

I want the ternary statement to check if something exists then if it does to run the map

Answer 5

Here an example I could show according to your recipes app roughly.
class App extends React.Component {
constructor(props) {
super(props);
this.state = {
recipes: [
{
recipe: "Dish Chinese 1",
type: "Chinese"
},
{
recipe: "Dish Usa 1",
type: "American"
},
{
recipe: "Dish Chinese 2",
type: "Chinese"
},
{
recipe: "Dish Usa 2",
type: "American"
},
]
}
}
render() {
return (
<div>
<h3>Chinese Recipes</h3>
<ul>
{ this.state.recipes.map((recipe, id) => recipe.type=='Chinese' ? <li>Recipe: {recipe.recipe} </li> : null ) }
</ul>
</div>
);
}
}
