What is the standard convention naming for property inside object?

camelCase

or

snake_case?

Here's an example:

let objPerson = {
    first_name: 'first',
    last_name: 'last'
};

or

let objPerson = {
    firstName: 'first',
    lastName: 'last'
};

Any remendation for a site to learn naming standardization of objects? I tried to google it but couldn't find an answer. Also the name of the object should be objPerson or ObjPerson because it is an object

• 1 You can choose - only real convention for name format is to start constructor and classes with a capital (and even then it's your own choice). – Jack Bashford Commented Mar 29, 2019 at 8:52
• i would go for the second option, because it is shorter to write and underscores makes code nervous. – Nina Scholz Commented Mar 29, 2019 at 8:54
• PascalCase for classes and camelCase for the rest are conventional in JS. There's no official standard. – Estus Flask Commented Mar 29, 2019 at 9:08
• There is no rule, however there is a rule that string literals should be terminated. – trincot Commented Mar 29, 2019 at 9:12
• As other have said, it's a matter of personal preference (I'm on board with @estus). Whatever you decide on, it might be a good idea to set up eslint and set a rule with your choice, so you are consistent. – Atheist Commented Mar 29, 2019 at 9:31

It's not really a standard, but i've seen more snake case in my days. You can choose whatever you like, it's just important that you use the same type during a project.
