JavaScript labels

In JavaScript, the label statements are written as statements with a label name and a colon.

Syntax:

break statements: It is used to jump out of a loop or a switch without a label reference while with a label reference, it is used to jump out of any code block.
```
break labelname; 
```
continue statements: It used to skip one loop iteration with or without a label reference.
```
continue labelname;
```

Example: This example uses break-label statements.

Javascript

let val = ["Geeks1", "Geeks2", "Geeks3",
    "Geeks4", "Geeks5"];
let print = "";
 
breaklabel: {
    print += val[0] + "\n" + val[1] + "\n";
    break breaklabel;
    print += val[2] + "\n" + val[3] + "\n" + val[4];
}
 
console.log(print);

Output

Geeks1
Geeks2

Example: This example uses the continue label.

Javascript

outer: for (let i = 1; i <= 2; i++) {
    inner: for (let j = 1; j <= 2; j++) {
        if (j === 2) {
            console.log("Skipping innerLoop iteration", i, j);
            continue inner; // Continue innerLoop iteration
        }
        console.log("GeeksInner", i, j);
    }
    console.log("GeeksOuter", i);
}

Output

GeeksInner 1 1
Skipping innerLoop iteration 1 2
GeeksOuter 1
GeeksInner 2 1
Skipping innerLoop iteration 2 2
GeeksOuter 2

Example: This example illustrates without using any label.

Javascript

let val = ["Geeks1", "Geeks2", "Geeks3", "Geeks4"];
let val1 = ["Geeks", "For", "Geeks"]
 
let print = "";
 
labelloop: {
    print += val1[0] + "\n";
    print += val1[1] + "\n";
    print += val1[2] + "\n";
}
 
print += "\n";
 
labelloop1: {
    print += val[0] + "\n";
    print += val[1] + "\n";
    print += val[2] + "\n";
    print += val[3] + "\n";
}
 
console.log(print);

Output

Geeks
For
Geeks

Geeks1
Geeks2
Geeks3
