How to parse a string in JavaScript based on comma as a delimiter?-CodePudding

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.

this way

let band = "John,Paul,George,Ringo";

let [name1,name2,name3,name4] = band.split(',')

console.log( name1 )
console.log( name2 )
console.log( name3 )
console.log( name4 )
