reduce params in react es6

Code can be cleaned by reducing number of params sent to function. Sending a value to function? this.state.something can directly set in function call.

example

Instead of this

renderBlock = (someFlag) => {...}

return({

{this.renderBlock(this.state.someFlag)}

})

Use this

...
renderBlock = (someFlag = this.state.someFlag) => {...}

return({

{this.renderBlock()}

})
...
