In a previous post, I was explaining how a
that = this assignment was required to preserve the value of the
this variable in certain scenarios. This post will focus on how to resolve them using arrow functions.
When you go through some of the popular JS libraries you might start noticing this peculiar line all over the place.
that = this that.someFunction();
First impressions, you could figure out that it had something to do with the value of the variable
this being inconsistent, so they had to store in a variable and use it later. So I did some digging into it and found out why this assignment was a necessity back then and how we can overcome them.
