is actually the summation of the Fibonacci series, using a Y fixed point combiner with a little bit of skill.
except for the Y fixed point combiner, it is a simple recursion.
derive Y group zygote by JavaScript
stay away from the programmer
Fibonacci item 10, that is, this number is equal to the sum of the first two terms
Fibonacci sequence summation
is actually a recursive
but you can't read it. The es6 structure assignment is more concise
. It's best to check whether it's number or a lot of useless numbers

A solution that conforms to the meaning of the question function unique(arr) { const res = new Map(); return arr.filter((a) => !res.has(a) && res.set(a, 1)) } because map key is unique, you can change the an in res.has (a) to whate...
