Designing a star pattern in React Native

I was trying to draw the star patter in react native where instead of stars, there are suppose to be square boxes.
Star pattern would look like this
****
****
****
****
****
In Vanila JS, it would look like
let rows=5;
for(let i=1; i <= 5; i++) {
for(let j=1; j<=5; j++){
document.write('*');
}
document.write('<br />');
}
But that's vanila JS and I want to make the same in React-native functional component and then display it in JSX
Consider this my functional component in react native
let numberOfBoxesRequired = 4;
let array =
const gridBoxes = (props) => {
for (let i=0; i<numberOfBoxesRequired; i++) {
for (let j=0; j<numberOfBoxesRequired; j++) {
}
}
return (
<View style={mainGridBox}>
</View>
)
}
Question: How can I do it?

It is the same in vanilla JavaScript and React:
const starLines = Array(4).fill('*'.repeat(4));
Once there's data, it can be output in a way that is specific to current application.
In plain JavaScript:
document.write(starLines.join('<br />'));
In React Native:
<View style={mainGridBox}>{starLines.map(line => <Text>{line}</Text>)}</View>

First you need to render your boxes:
let numberOfBoxesRequired = 4;
const gridBoxes = (props) => {
let boxes = ;
for (let i=0; i<numberOfBoxesRequired; i++) {
for (let j=0; j<numberOfBoxesRequired; j++) {
boxes.push(<Box />); // assume Box is your box component
}
}
return (
<View style={mainGridBox}>
{boxes} // render the boxes
</View>
)
}
Then you will have to style your gridBox:
.mainGridBox {
flex: 1,
flexWrap: "wrap";
}
.box {
flexBasis: 0.25; // this will make a box fill 25% of the container width
width: 30; // example width
height: 30; // example height
}
This is the closest to your implementation, but I suggest you use Array.map() like estus pointed out in his answer.

We declare it in the function scope, because it is only used inside the function.
