const params = [ "hello", true, 7, { first: "first", second: "second" } ] const other = params.slice()
spread operator
const params = [ "hello", true, 7, { first: "first", second: "second" } ] const other = [ ...params ]
FromArray method
var FromArray = function (array) { var temp = [] for (var i = 0; i < array.length; ++i) { temp.push(array[i]) } return temp } const params = [ "hello", true, 7, { first: "first", second: "second" } ] const other = FromArray(params)
