TypeScript - let & backticks
What is let:
* Its like Javascript var keyword;
* In var keyword in javascript have some gotchas and pitfalls like scoping, capturing etc.,
* let keyword is solving those issues as well.
Typescript strongly Typed:
let found: boolean = true;
found = 0; // Compile time error will throw if you assign 0. mismatch the datatype.
let data: any = 50.0;
data = "Vinoth"; // true
data = false; // true
Try to avoid use any, because we will lose type safty.
Use backticks:
console.log("Hi " + firstname + " " + lastname);
console.log('Hi ${firstname} ${lastname}');
