Thanks for your suggestion

really like github themes i want to recommand a personal favorable theme: One dark pro

Sometimes, the type of data which are retrieved from apis is bitter vague, such as { code: 2, name: 'fengxh', type: 'human' } or { code: '2', type: 'clothes' }, from two different apis. So more codes to directly use ===, unless a workaround +code === 2. But I still recommend using ===

I'm sorry, but there is an error in javascript code about ternary operator let age = 17 if(age >= 18){ console.log(" You are old enough to vote"); }else{ console.log("Come back when you are 18"); } // Ternary Operator if age >= 18 ? console.log(" You are old enough to vote") : console.log("Come back when you are 18"); // here we don't need if identifier, just remove it

Do you have any other programming languages experience? If you are an absolute beginner, there is a long way to go in front of you.

I have used this one before. But I will change theme every two or three months

Hi Tomasz: I'm a middle level front-end engineer, and my projects are mostly about websites and back-end management systems. I have worked for 5 years after graduated from high school, and now I get a little confused about how to reach a higher level, how to prep myself to build more featured works. And what's your path to senior engineer. Thanks a lot.

You can use reduce to finish the multiply action. function multiply(arr) { if (arr.length <= 0) return 1; return arr.reduce((result, number) => { return result * number; }, 1); } Another thing about recursion is tail optimization, it can reduce the usage of call stack to minimize space complexity.

It is exactly the problem. I always pass the id or code field as key in React/Vue. shortedRow.map(data => <Component key={data.id} />)

Congratulations man. I'm also finding my new job recently, and wish I can find my perfect position and a better tomorrow
