How to useString Constructor in Typescript
The String constructor can also be employed to convert boolean values to their string representation. By passing a boolean value to the String constructor, it automatically converts it into its string equivalent.
Syntax:
let bool: boolean = true;
let str: string = String(bool);
Example: In this example we converts a boolean value to its string representation using the String constructor and logs it. The result is either ‘true’ or ‘false’.
const myBool: boolean = true;
const boolAsString: string = String(myBool);
console.log(boolAsString);
Output:
true
How to Convert a Bool to String Value in TypeScript ?
When we talk about converting a boolean to a string value in TypeScript, we mean changing the data type of a variable from a boolean (true or false) to a string (a sequence of characters). To convert a bool to a string value in TypeScript we have multiple approaches.
Example: let’s say you have a variable isLogged
that represents whether a user is logged in or not:
const isLogged: boolean = true;
If you need to use this boolean value as a string, you can convert it to a string representation using various methods, as discussed earlier. The result would be a new variable with a string data type:
const isLogged: boolean = true;
const isLoggedAsString: string = isLogged.toString();
Now, isLoggedAsString
holds the string representation of the boolean value true
as “true”. This can be useful when you need to concatenate it with other strings, display it in a user interface, or pass it to functions or APIs that expect string values.
Below are the approaches used to Convert a bool to a string value in TypeScript:
