Question 285689 in React native Question posted in
The official React Native documentation can be found here.

What is the difference between these two children uses in React Native?

I’m confused on these different uses of children and why they work. Can anyone explain? Is children a default parameter for react native functions?

const Component = ({
  children = <Text>Insert Icon</Text>,
}) => {
  return ( {children} );
};

const Component = ({
  {children},
}) => {
  return ( {children} );
};

Not a problem, just want an explanation

    Is children a default parameter for react native functions?

    Yes. You can set default value for parameters in function:

    const multiply = (a, b = 1) => {
  return a * b;
}

console.log(multiply(5, 2));
// Expected output: 10

console.log(multiply(5));
// Expected output: 5

    when you set

    ({
  children = <Text>Insert Icon</Text>,
})

    it’s mean if children = null, hence children = <Text>Insert Icon</Text>
