After setting the value of input to this.state.value the possibility of typing in there is blocked.

Console doesn't throw any error. here is the code of my AddPlayerForm component: 

import React, { Component } from 'react';

class AddPlayerForm extends Component {

  state = {
    value: ''
  };

  handleValueChange = (e) => {
    this.setState = ({ value: e.target.value });
  }

  render() {
    return (
      <form>
        <input
          type="text"
          value={this.state.value}
          onChange={this.handleValueChange}
          placeholder="Enter a player's name"
        />

        <input
          type="submit"
          value="Add Player"
        />
      </form>
    );
  }
}


export default AddPlayerForm;

Remember that setState is a function.

handleValueChange = (e) => this.setState({ value: e.target.value });
