Guide on accomplishing masking in Angular 5

I'm curious if it's achievable to design a mask in Angular 5 that appears as follows:

XXX-XX-1234

Moreover, when the user interacts with the text box by clicking on it, the format should transform into:

1234121234

Appreciate your help!

To modify it, you can include a regular expression.

newValue = value.replace(/\D/g, '').match(/(\d{0,3})(\d{0,2})(\d{0,4})/);

This function will produce 4 arrays that you can combine in the way you prefer. For instance,

!newX[2] ? newX[1] : `${newX[1]}-${newX[2]}${newX[3] ? '-' + newX[3] : ''}`;
