Javascript Regex for .ts extentions

Question

Could you please give me a javascript regex which match all .ts files except the files ending with page.ts and d.ts

ex :

• home.inventory.ts -> match
• player.ts -> match
• book.page.ts -> not match
• component.d.ts -> not match

Answer 1

Use negative lookahead to prevent *.d.ts and *.page.ts from matching.

/^(?!.*(page|d)\.ts$).*\.ts$/
  ^^^^^^^^^^^^^^^^^^^ NEGATIVE LOOKAHEAD
