Limiting the times that .split() splits, rather than truncating the resulting array

Question

Really, pretty much what the title says.

Say you have this string:

var theString = \"a=b=c=d\";

Now, when you run theString

Answer 1

const theString = "a=b=c=d";
const [first, ...rest] = theString.split("=");
const second = rest.join("=")
console.log(first, second)
