I'm new in JavaScript. I was programming and I saw some used
const PI : 3.14
I'm puzzled how ':' notion can be used to assign values to variables. Can anyone explain to me when ':' is used to assign values to variables? That'll be really helpful ^^
If you are just assigning a variable, you can't use a colon. What you want is const PI = 3.14. Colons can be used for other purposes however, for example, setting keys in an object:
const myObject = {
key: "my new value"
}
NO! That is the wrong syntax and will throw error in JS.
Either you write
const PI = 3.14;
OR
const Obj1 = {PI: 3.14}
These, are the valid syntax in JS.
