Approach 1 - Use Graph API
If you want to use Graph api, follow below steps,
- go to below URL
https://developer.microsoft.com/en-us/graph/graph-explorer - Sign in with your O365 details.
 
- Once you are logged in, click on "my profile" and it will get all your details.
 
How to use this in code,  I will write another blog for same.
Approach 2 - Use browser Console
Some of the properties are available using "_spPageContextInfo". Like user display name, user email address and user login name.
- user display name - _spPageContextInfo.userDisplayName
 - user email - _spPageContextInfo.userEmail
 - user login name - _spPageContextInfo.userLoginName
 - user Id - _spPageContextInfo.userId
 
Approach 3 - Use Rest API (Ajax request)
To get other details you need to use below ajax request:
function getCurrUsrImg(){
var siteurl = _spPageContextInfo.webAbsoluteUrl;
Var usrId = _spPageContextInfo.userId;
var userURL = siteurl + "/_api/web/SiteUserInfoList/Items('"+usrId+"')";
$.ajax({
url: userURL,
method: "GET",
headers: { "Accept": "application/json; odata=verbose" },
async: true,
success: function (data) {
getCurrUserIMGSuccess(data.d);
},
error: function (data) {
console.log("Error: "+ data);
}
});
}
function getCurrUserIMGSuccess(res){
//console.log("llll");
var uHTMLIMG = "";
if(res.Picture != null){
uHTMLIMG = "<img src='"+res.Picture["Url"]+"'>";
}
$('#divCuserimg').html("");
$('#divCuserimg').html(uHTMLIMG);
}
You can get below list of fields with this call:
- Id
 - ContentTypeId
 - Title (full name - love thakker)
 - Name (domain name - i:0#.f|membership|love.thakker)
 - MobilePhone
 - SipAddress
 - Deleted (true / false)
 - Picture ( look up - expand with description and URL)
 - Department
 - JobTitle
 - FirstName
 - LastName
 - WorkPhone
 - UserName
 - GUID
 - Modified
 - Created
 - AuthorId
 - EditorId
 
Approach 4 - Use People Manager api (Ajax request)
If you want even more details than this then you can use below service call
$.ajax({  
            url: _spPageContextInfo.siteAbsoluteUrl + "/_api/SP.UserProfiles.PeopleManager/GetMyProperties",  
            headers: { Accept: "application/json;odata=verbose" },  
            success: function (data) {  
                try {  
                    //Get properties from user profile Json response  
                    userDisplayName = data.d.DisplayName;  
                    AccountName = data.d.AccountName;  
                    var properties = data.d.UserProfileProperties.results;  
                    for (var i = 0; i < properties.length; i++) {  
                        var property = properties[i];  
                        if (property.Key == "Office") {  
     location = property.Value;
                        }  
                    }
                } catch (err2) {  
                  console.log('error');
                }  
            },  
            error: function (jQxhr, errorCode, errorThrown) {  
                alert(errorThrown);  
            }  
        });  
}
Below is list of columns that you will get when you use this:
