3. Use the spread function with the spread operator to concatenate multiple arrays. Here's an example:

index.ts
const arr1: string[] = ['apple', 'banana'];
const arr2: string[] = ['orange', 'grape'];
const arr3: string[] = ['peach', 'kiwi'];
const result: string[] = spread([...arr1, ...arr2, ...arr3]);

console.log(result); // ['apple', 'banana', 'orange', 'grape', 'peach', 'kiwi']

Note that the spread function returns a new array that concatenates the input arrays. If you need to concatenate the input arrays in place, you can use the concat method of the Array class instead.
