AAAAAAAAAAAAAAA * fix: separate the test Okay apparently the test does not work unless we separate it into a different `it` statement. >:( >:( >:( >:( Co-authored-by: Sujal Gupta <55016909+heysujal@users.noreply.github.com> Co-authored-by: Noor Fakhry <65724923+NoorFakhry@users.noreply.github.com> Co-authored-by: Oliver Eyton-Williams <ojeytonwilliams@gmail.com> Co-authored-by: Nicholas Carrigan (he/him) <nhcarrigan@gmail.com>

--description--
Hay otra manera de acceder al state
de un componente. En el método render()
, antes de la sentencia return
, se puede escribir JavaScript directamente. Por ejemplo, puedes declarar funciones, acceder a datos de state
o props
, realizar cálculos sobre estos datos, etc. Luego, puedes asignar cualquier dato a las variables, a las que tienes acceso en la sentencia return
.
--instructions--
En el método de renderización de MyComponent
, define una const
llamada name
y ponlo igual al valor del nombre en el state
del componente. Debido a que puedes escribir JavaScript directamente en esta parte del código, no tienes que incluir esta referencia entre llaves.
A continuación, en la sentencia return, renderiza este valor en una etiqueta h1
usando la variable name
. Recuerda, necesitas usar la sintaxis JSX (llaves para JavaScript) en la sentencia return.
--hints--
MyComponent
debe tener una clave name
con valor freeCodeCamp
almacenado en su estado.
assert(
Enzyme.mount(React.createElement(MyComponent)).state('name') ===
'freeCodeCamp'
);
MyComponent
debe renderizar un encabezado h1
incluido en un solo div
.
assert(
/<div><h1>.*<\/h1><\/div>/.test(
Enzyme.mount(React.createElement(MyComponent)).html()
)
);
La etiqueta h1
renderizada debe incluir una referencia a {name}
.
(getUserInput) =>
assert(/<h1>\n*\s*\{\s*name\s*\}\s*\n*<\/h1>/.test(getUserInput('index')));
El encabezado h1
renderizado debe contener texto renderizado desde el state del componente.
async () => {
const waitForIt = (fn) =>
new Promise((resolve, reject) => setTimeout(() => resolve(fn()), 250));
const mockedComponent = Enzyme.mount(React.createElement(MyComponent));
const first = () => {
mockedComponent.setState({ name: 'TestName' });
return waitForIt(() => mockedComponent.html());
};
const firstValue = await first();
assert(firstValue === '<div><h1>TestName</h1></div>');
};
--seed--
--after-user-code--
ReactDOM.render(<MyComponent />, document.getElementById('root'))
--seed-contents--
class MyComponent extends React.Component {
constructor(props) {
super(props);
this.state = {
name: 'freeCodeCamp'
}
}
render() {
// Change code below this line
// Change code above this line
return (
<div>
{ /* Change code below this line */ }
{ /* Change code above this line */ }
</div>
);
}
};

class MyComponent extends React.Component {

super(props);
this.state = {
name: 'freeCodeCamp'
}

// Change code below this line
const name = this.state.name;
