This example demonstrates a specific issue that needs to be addressed.
let head = [["title", "value"], ["a", 1]];
let tail = [["b", 2], ["c", 3]];
let all = head.concat (tail);
The output is as expected:
[["title", "value"], ["a", 1], ["b", 2], ["c", 3]]
However, the desired outcome is slightly different and currently not functioning properly.
let head = [["title", "value"]];
let tail = [["a", 1], ["b", 2], ["c", 3]];
let all = head.concat (tail);
An error occurs when attempting to implement this change:
Argument of type '(string | number)[][]' is not assignable to parameter
of type 'string[] | string[][]'.
Type '(string | number)[][]' is not assignable to type 'string[][]'.
Type '(string | number)[]' is not assignable to type 'string[]'.
Type 'string | number' is not assignable to type 'string'.
Type 'number' is not assignable to type 'string'.
One solution involves converting the numbers in the 'tail' array into strings, although this may not always be feasible.
If avoiding such conversions is a requirement, how can this code be modified to achieve the desired functionality?
Your help would be greatly appreciated. Thank you!
