Uncaught TypeError: this.state.data.map is not a function

Question

I am new to React, have seen some of the similar issues, but didn’t find why this happens. I am getting an “Uncaught TypeError: this.state.data.map is not a function”. Here

Answer 1

First you must split data to an array, then you may use the map function. Instead of

 this.state.data.map

use

this.state.data.split('').map()
