I recently received help from a friend who provided me with a custom filter in AngularJS to capitalize one of the values in my object within an array. However, due to time constraints, he was unable to explain the code to me. I am reaching out to see if anyone would be willing to assist me in understanding this block of code:
.filter('capitalizetext', function() {
return function(name) {
name = ( name === undefined || name === null ) ? '' : name;
return name.toString().toLowerCase().replace( /\b([a-z])/g, function(change) {
return change.toUpperCase();
});
};
})
The first part that is unclear to me is:
name = ( name === undefined || name === null ) ? '' : name;
I'm unsure why he implemented this.
The second part that I’m struggling to grasp is:
return name.toString().toLowerCase().replace( /\b([a-z])/g,
I understand that he is converting the string to lowercase in order to capitalize it later on, but could you please explain what this: ( /\b([a-z])/g signifies?
I would greatly appreciate any assistance in clarifying this code. Thank you!
