<\/span><\/h2>\n\n\n\nslice() method returns a copy of a subset of an array, without changing original array. It is a built-in method available for every array. Here is its syntax.<\/p>\n\n\n\n
array.slice(start, end)<\/pre>\n\n\n\nIn the above command, you need to specify the start and end position of the items to be extracted and returned. They are both optional and can be omitted. If you do not specify them, then slice() method will return a copy of the entire array. Here is an example to demonstrate it.<\/p>\n\n\n\n
var a = [1, 2, 3];
b=a.slice();
console.log(b); \/\/ output is [1, 2, 3]<\/pre>\n\n\n\nPlease note, the new array will be a shallow copy of original array. If you have basic data types like numbers and strings, then their clones will be present in new array. If you have references to functions and other complex data types, then they will continue to refer to the original array.<\/p>\n\n\n\n
