Total spread 26947.0 Ops/sec
Script Preparation code:
​x
 
start = 0
stop = 10000
x = []
​
for(var i = 0; i < 10000; i++) {
  x.push(i)
}
Tests:

  • Push single

     
    y = []
    ​
    x.forEach(e => y.push(e))

  • Push spread

     
    y = []
    ​
    y = y.push(...x)

  • Total spread

     
    y = []
    ​
    y = [...y, ...x]
