The 'toString()' Method
The toString() method is used for conversion and concatenating. It may the change the return value of a variable to a string (or text). The parameters for this method are usually left empty, although, custom parameters may be entered to override the orignal use of the method.
let num = 26; let text = num.toString(); console.log(text);
The variable ends up with a string data type
The 'valueOf()' Method
The valueof() method is used to return the value of the object being called, or the object itself. This method may convert an object to a primitive value, which is a value that cannot be changed. The paramter takes the name of the variable being instantiated.
let string = "Hello World!"; console.log(string.valueOf(string));
The logged output will display "Hello World!" (However, without the quotes). This would be a string data type
The 'toLowerCase()' Method
The toLowerCase() method will make the target variable appear with lowercase text. The parameter is left empty for this method.
let lwcSandwich = "mcChicKen"; lcSandwich = lwcSandwich.toLowerCase(); console.log(lcSandwich);
The result will change from 'mcChicKen' to 'mcchicken', without the quotes, being a string data type
The 'toUpperCase()' Method
The toLowerCase() method will make the target variable appear with uppercase text. The parameter is left empty for this method.
let upcSandwich = "MCCHICKEN"; ucSandwich = upcSandwich.toUpperCase(); console.log(ucSandwich);
The result will change from 'mcChicKen' to 'MCCHICKEN' without the quotes, being a string data type
