Typescript - Stripping multiple characters from the start and end of a string/Retrieving attributes of a JSON list element

My challenge involves a string like the following :

"{"element":"634634"}"

My goal is to eliminate {"element":" which remains constant, as well as the final character "}. The only variable component is 634634. How can I achieve this?

Alternatively, can anyone provide guidance on the following:

I have an array like the one shown below:

To create an array of strings from the given array, you can utilize the Array.map() method for iteration:

const listElement = [
  '{"element":"734734"}',
  '{"element":"utruytuyt"}',
  '{"element":"07078"}',
  '{"element":"khgkhg45"}',
];

const result = listElement.map((str: string) => JSON.parse(str).element);

console.log(result);

If you're looking to manipulate a string, I recommend utilizing JavaScript for the task.

One approach is to use the replace function to remove a specific character from the string. For instance, you can achieve this by executing the following code:

replace('}', '');
