Optimizing your App and Using Components to Display Data Chapter 3
field = field.toLowerCase();
result =
field.includes(query.toLowerCase());
}
}
}
return result;
},
isActiveFilterSelected() {
return (this.filterField === 'isActive');
}
}
});
Looking at the preceding code, there are some improvements we can make. These include:
Reducing the number of filter variables and grouping logically
Combining the format functions
Reducing the number of hard-coded variables and properties
Re-ordering methods into a more logical order
We'll cover these points individually so we have a clean code base for building components
with.
Reducing the number of filter variables and
grouping logically
The filtering currently uses up three variables, filterField, filterQuery,
and filterUserState. The only thing that currently links these variables is the name,
rather than being in an object of their own to link them systematically. Doing this avoids
any ambiguity as to whether they are related to the same component or just coincidentally
the same. In the data object, create a new object titled filter and move each variable
inside:
data: {
people: [..],
currency: '$',
filter: {
field: '',
query: '',
userState: '',
}
}
