Const App references two other components above it. At run time, it compiles successfully with no errors but I'm not getting the result I want.
Inside const App = () => {}, I have no problems rendering the Header tag within the return statement. In fact, it does what I want it to do which is to print "Half Stack application development" as a header in html.
The problem is with the Total tag underneath it. Underneath the header I want to render the number 342 as a paragraph tag onto the web page, but its not working.
Any help would be greatly appreciated to a newbie like me who just started learning React. Thank you :)
// Header takes care of rendering the name of the course.
const Header = (props) => {
return (
<div>
<h1>{props.course}</h1>
</div>
)
}
// Total renders the total amount of exercises.
const Total = (props) => {
return (
<div>
<p>Total number of exercises:{props.parts}</p>
</div>
)
}
// Header takes care of rendering the name of the course.
const App = () => {
const course = {
name: 'Half Stack application development' ,
parts: [{name:'One' , exercises:342}]
}
return (
<div>
<Header course={course.name} />
<Total parts={course.parts.exercises} />
{/*
<Content parts={parts} />
*/}
</div>
)
}
ReactDOM.render(<App />, document.getElementById('root'))
This is not really a react problem but a problem with accessing the parts array :
Try:
<Total parts={course.parts[0].exercises} />
