How to filter and delete filtered elements in an array with JavaScript?

To filter and delete filtered elements in an array with JavaScript, we use the splice and findIndex methods.

For instance, we write

const a = [{ name: "tc_001" }, { name: "tc_002" }, { name: "tc_003" }];
a.splice(
  a.findIndex((e) => e.name === "tc_001"),
  1
);

to call a.findIndex with a callback that checks if name is 'tc_001' in the object being looped through to get the index with name property equal to ‘tc_001’ina`.

Then we call splice with the index and 1 to remove the item in a with such condition.
