I want to check if an array contains role. If it does, I want to move the role to the front of the array.

var data= [email,role,type,name];

if (role in data) data.remove(data.indexOf(role)); data.unshift(role)

data;

Here, I got the result:

[role, email, role, type, name]

How can I fix this?

You can sort the array and specify that the value role comes before all other values, and that all other values are equal:

var first = role;

data.sort(function(x,y){ return x == first ? -1 : y == first ? 1 : 0; });
