I was using the code from this example: Link
I straight copied the code from it but notice that there are serval syntax errors appear on this line:
return <TagsInput renderInput={autocompleteRenderInput} value={this.state.tags} onChange={::this.handleChange} />
These errors complain about the two columns from 'onChange={::this.handleChange}' which I have never seen before.
Should I just simply get rid of them?
