JavaScript .slice()

The .slice() method selects and returns a selected portion of a string.

Syntax

string.slice(start);

string.slice(start, stop);

• The start index is optional and begins at zero (inclusive) by default.
• The stop index is also optional and defaults to the length of the string (not inclusive).

Example

In the example below, a smoothie string is created. Next, the .slice() method is used to extract substrings for the berry variable:

let smoothie = 'mango strawberry pineapple';

let berry = smoothie.slice(6, 16);

console.log(smoothie);

console.log(berry);
