# Intuition\n<!-- Describe your first thoughts on how to solve this problem. -->\nWe need to concatenate the input array with itself to create a new array where the first half and the second half are identical. This can be efficiently achieved using the spread operator.\n\n# Approach\n<!-- Describe your approach to solving the problem. -->\n1. Use the spread operator (`...`) to create a new array containing two copies of the input array.\n2. Return the resulting concatenated array.\n\n# Code\n```javascript []\n/**\n * @param {number[]} nums\n * @return {number[]}\n */\nvar getConcatenation = function(nums) {\n    return [...nums,...nums]\n};\n```\n\n```typescript []\nfunction getConcatenation(nums: number[]): number[] {\n    return [...nums, ...nums];\n}
