How to add two strings together in ts or css

Question

I want to add in ts (solo + learn = Sololearn)

Answer 1

let a: string = 'Solo';
let b: string = 'learn';
let c: string = a + b;
console.log(c);

Answer 2

JavaScript/TypeScript:
console.log("solo"+"learn")
CSS is not a programming language, it is a style language. You can't do that with CSS.

Answer 3

Var a: string="solo";
Var b: string="learn";
Var c= a+b;
console.log(c);

in typescript and javascript, one should avoid using var and consider using const and let instead.

var is an old convention that has a lot of undesired behavior that can lead to unexpected bugs.

consider it a bad keyword you shouldn't be using anymore.

unfortunately, you can still find code examples using var. maybe the authors just don't care, or they're old tutorials and documentations.

try Googling:

the AI gives a pretty good summary of the cons ...
