Benchmark: Remove all except last

Remove all except last (version: 0)

Script Preparation code:

var array = []
for(let i = 0; i < 1000; ++i) array.push(i*i*i);

Tests:

array.slice()
array = array.slice(array.length - 1)
array.splice()
array.splice(0, array.length - 1)
array.shift() n times
for (let n = array.length - 1, i = 0 ; i < n ; i++) array.shift()
array.shift() while length is longer
while(array.length > 1) array.shift()
array.slice() #2
array = array.slice(array.length - 1)
array.splice() #2
array.splice(0, array.length - 1)
array.shift() n times #2
for (let n = array.length - 1, i = 0 ; i < n ; i++) array.shift()
array.shift() while length is longer #2
while(array.length > 1) array.shift()
