the first article asked me to pay for membership since I’d read all the free stories I’m allowed?
When iterating through an array too often, it can slow down the program- especially if it’s a big array. The datatype can be converted using a hash function, like making a const of the array using .map.
When several functions are doing similar jobs, thus creating redundant code, its best to combine them into a single function the takes a larger set of data or more parameters to do multiple tasks with the same function.
If there’s a large function doing several things, and you have what you need, you can use an if statement to check for a condition to have been met and if so, return;.
Variable names should reflect what they’re doing so the code can be read like sentances, even if it means adding lines in which const something = whatItRefersTo[x];
