This article mainly introduces "how to achieve arithmetic addition in javascript". In daily operation, I believe that many people have doubts about how to achieve arithmetic addition in javascript. Xiaobian consulted all kinds of materials and sorted out simple and easy-to-use operation methods. I hope it will be helpful to answer the doubts about "how to achieve arithmetic addition in javascript". Next, please follow the editor to study!

1. Use the "+" operator and the syntax "axib".

Var n = 5; / / define and initialize any numeric console.log (NaN + n); / / add NaN to any Operand, the result is NaNconsole.log (Infinity + n); / / Infinity plus any Operand, the result is Infinityconsole.log (Infinity + Infinity); / / Infinity and Infinity add, the result is Infinityconsole.log ((- Infinity) + (- Infinity); / / negative Infinity addition, the result is negative Infinityconsole.log ((- Infinity) + Infinity) / / plus or minus Infinity, the result is NaN

2. Use the "+ =" operator and the syntax "axiomb".

Var axiom 1, console.log 2, console.log (c), console.log (d), etc.

3. Use the "+ +" increment operator and the syntax "axiom +" or "+ + a".

Var a = b = c = 4 console.log (aquired +); / / return 4, assign first, then increment the result unchanged console.log (+ + b); / / return 5, increment first, then assign, add 1console.log (C++); / / return 4, assign first, then increment, the result remains unchanged console.log (c); / / return 5, add 1console.log (+ + c) to the value of the variable / / return 6, increment first, then assign the value, add 1console.log (c) to the operation result; / / return 6 to this point, the study on "how to implement arithmetic addition in javascript" is over, hoping to solve everyone's doubts. The collocation of theory and practice can better help you learn, go and try it!
