Computed properties of Vue

This time I will bring you the calculation properties of Vue . What are the precautions when using Vue to calculate properties? The following is a practical case, let’s take a look.

VueObject, according to the current learning progress, can be divided into:

where el represents the role of the HTML element ;

data represents all data in el;

methods represents events on all elements in el;

computed represents calculated attributes , used to calculate variables in data to generate new required data, such as averages, etc. Different from methods, the computed value will only be recalculated when the data changes, while the methods method needs to be called at a time. Will reduce performance.

I believe you have mastered the method after reading the case in this article. For more exciting information, please pay attention to other related articles on the php Chinese website!
