for i of

for i in
const testArray = [ 1, 2, 3, 4, 5, 6, 7, 8, 9, 0 ] const newArray = [] for (const i in testArray) { newArray[i] = testArray[i] }
for i length first
const testArray = [ 1, 2, 3, 4, 5, 6, 7, 8, 9, 0 ] const length = testArray.length const newArray = [] for (let i = 0; i < length; i++) { newArray[i] = testArray[i] }
for i length every
const testArray = [ 1, 2, 3, 4, 5, 6, 7, 8, 9, 0 ] const newArray = [] for (let i = 0; i < testArray.length; i++) { newArray[i] = testArray[i] }
while crazy
const testArray = [ 1, 2, 3, 4, 5, 6, 7, 8, 9, 0 ] let i = testArray.length const newArray = [] while (~--i) { newArray[i] = testArray[i] }
while boring
const testArray = [ 1, 2, 3, 4, 5, 6, 7, 8, 9, 0 ] let i = -1 const newArray = [] while (i++ < testArray.length) { newArray[i] = testArray[i] }
slice
const testArray = [ 1, 2, 3, 4, 5, 6, 7, 8, 9, 0 ] const newArray = testArray.slice()
