Objects are not valid as a React child

May 8, 2023 by Tarik

timeElapsed is an object, React doesn’t know how to render this:

  <View style={[styles.timerContainer, this.borderColor('#ff6666')]}>
    {this.state.timeElapsed}
  </View>

Try changing this.state.timeElapsed for a string like for example:

  <View style={[styles.timerContainer, this.borderColor('#ff6666')]}>
    {this.state.timeElapsed.toString()}
  </View>
