How to use v-for in Vue
Rendering dynamic lists and iterating over data is fundamental for creating responsive Vue applications with data tables, navigation menus, and content lists.
As the creator of CoreUI, a widely used open-source UI library, I’ve implemented v-for in countless Vue components for rendering data grids, dropdown options, and dashboard widgets in enterprise applications.
From my expertise, the most efficient approach is to use the v-for
directive with proper key attributes.
This method ensures optimal performance through Vue’s virtual DOM diffing algorithm and prevents rendering issues during list updates.
How to use ngFor in Angular
Rendering dynamic lists is fundamental in Angular applications, especially for dashboards, data tables, and any component displaying arrays of data.
As the creator of CoreUI, a widely used open-source UI library, I’ve implemented ngFor in countless Angular components including data tables, navigation menus, and dashboard widgets.
From my expertise, the most efficient approach is to use the *ngFor
structural directive with proper TypeScript typing.
This method provides clean template syntax and excellent performance when combined with trackBy functions.
How to calculate the factorial of a number in JavaScript
Calculating factorials is important for mathematical computations, combinatorics, probability calculations, and implementing features like permutation generators or statistical analysis in JavaScript applications. With over 25 years of experience in software development and as the creator of CoreUI, I’ve implemented factorial calculations in components like mathematical utilities, educational tools, and data analysis features where precise mathematical operations are essential for accurate results. From my extensive expertise, the most straightforward approach for small numbers is using recursion, while iteration provides better performance and avoids stack overflow for larger numbers. Both methods have their place depending on the use case and performance requirements.
