To copy a deep array in JavaScript, you can use a combination of JSON.parse()
and JSON.stringify()
. Here's an example:
index.tsx329 chars11 lines
In this example, we use JSON.stringify()
to convert the original array to a JSON string, and then JSON.parse()
to parse that string back into a new array. This creates a new array with the same values as the original array, but they are stored in different memory locations. Therefore, modifying the original array will not affect the copied array, and vice versa.
