react-native - this.porps.inGrid is not a function - foreach

Question

I'm trying to display a nested array containing numbers. The array has 6 elements (arrays). Each nested array contains 6 further elements/numbers. I'm trying to display each number in a Square component. I've got an error: this.props.inGrid.foreach is not a function.
import React, { Component, PropTypes } from 'react';
import { View, StyleSheet } from 'react-native';
import Square from './Square';
import * as globalStyles from '../styles/global';
export default class Grid extends Component {
render() {
const row = [];
this.props.inGrid.foreach((r, i) => {
row.push(
<Square key={i} sqValue={r[i]} />
);
});
return (
<View style={styles.grid}>
{row}
</View>
);
}
}
Grid.propTypes = {
numbers: PropTypes.object
};
const styles = StyleSheet.create({
grid: {
backgroundColor: globalStyles.BG_COLOR,
flexDirection: 'row',
padding: 20,
justifyContent: 'center'
}
});
Below is the Square component:
import React, { PropTypes } from 'react';
import { View, Text, StyleSheet } from 'react-native';
import * as globalStyles from '../styles/global';
const Square = ({ sqValue }) => {
return (
<View style={styles.square}>
<Text>{sqValue}</Text>
</View>
);
};
Square.propTypes = {
sqValue: PropTypes.number
};
const styles = StyleSheet.create({
square: {
backgroundColor: globalStyles.BAR_COLOR,
width: 50,
height: 50,
borderWidth: 1,
borderStyle: 'solid',
borderColor: 'red'
}
});
export default Square;
What am I doing wrong?

It appears that you're calling:
this.props.inGrid.foreach
but the function is actually called forEach
