Is there any way in JavaScript to parse a string?
For example, I have this string named "band":
let band = "John,Paul,George,Ringo";
and I want to parse it based on comma as a delimiter. So, in the end I want to have four variables:
let name1 = "John";
let name2 = "Paul";
let name3 = "George";
let name4 = "Ringo";
How can I do that?
You can split the string on a comma:
let band = "John,Paul,George,Ringo";
let members = band.split(',');
let john = members[0];
let paul = members[1];
let george = members[2];
let ringo = members[3];
This will give you an array called members which lets you access them using an index either directly or via a loop.
Depending on what browsers/environments you may need to support, you can destructure the array too:
let band = "John,Paul,George,Ringo";
let [john, paul, george, ringo] = band.split(',');
If you want loop over the members:
let band = "John,Paul,George,Ringo";
let members = band.split(',');
for (let i = 0; i < members.length; i++) {
console.log(members[i]);
}This would loop over all members in the array and log them to console, which you can modify to perform other things on each item in the array.
