It is widely acknowledged among programmers that the more your code looks like math, the more correct it is. This has led to important advances such as Haskell programmers' use of single-character variable names or the Julia convention where 2x is syntactic sugar to write 2 * x. I propose, however, that we are missing one particular bit of necessary correctness. I believe that it is crucial for ECMA to implement a new syntax for dividing in JavaScript, namely:
L
const f = (x, b, k, L) => ---------------------------
1+Math.exp(-k * (x - b)
