Discord.js V12 找一个以某事开头的角色

Question

How could I make it so it finds a role that starts with for example Leader and it will find a role Leader of server for example... Please let me know:D current code:

        const leaderRole = message.guild.roles.cache.find(role => role.name == "Leader");
        const leaderMembers = message.guild.members.cache.filter(member => member.roles.cache.find(role => role == leaderRole)).map(member => member.user);

Answer 1

role.name.indexOf('Leader') !== -1

For case sensitivity.

role.name.toLowerCase().indexOf('leader')

eg

const leaderRole = message.guild.roles.cache.find(role => role.name.indexOf('Leader') !==-1 );
