Viewshow to remove this comma in the status
bot.on('message', message => {
if (message.content.startsWith('ch ')){
a = message.content
let str1= a
let str2= 'ch '
str3 = str1.split(str2)
var str4 = str3.toString()
bot.user.setActivity( { type: 'WATCHING' } , {name:str4} )
}
})
When I type "ch book", it become this :
a comma in front of the word.
How can I fix this? Thanks

Looks like you are simply trying to remove "ch " from the beginning of the string. You don't need split and arrays for that, you can just use .replace() :
bot.on('message', message => {
if (message.content.startsWith('ch ')){
bot.user.setActivity( { type: 'WATCHING' } , { name:message.content.replace('ch ','') })
}
})

String.prototype.split()
You should first understand the usage of this method first. This method splits a string into an array with each element delimited by the character of your choice, here a comma.
"ch, books".split(','); // returns ["ch", " books"]
Array.prototype.toString()
This method returns a string representation of the array, which would have comma-separated elements and you end up going back to square one!
["ch", " books"].toString(); // returns "ch, books"
Use String.prototype.replace() Instead
As long as you need to just sanitize string by removing commas or other special characters, use this method along with RegExp.
"ch, books, copies, notebooks".replace(/,/g, ''); // returns "ch books copies notebooks"
// further remove more characters such as hyphens
"ch, books, copies, note-books".replace(/,|-/g, ''); // returns "ch books copies notebooks"
