In Javascript, <\/a>both the spread <\/a>and rest <\/a>operators<\/a> have the same syntax which is three dots(\u2026)<\/strong> but they differ in their function. The main difference between them is that the spread operator expands the array into multiple elements while the resting operator<\/p>\n

Condenses them into a single element<\/p>\n

Merge two arrays using the spread operator<\/strong><\/p>\n

A Spread operator can be used to merge multiple arrays containing one or more elements into a single array.<\/p>\n

\"\"<\/p>\n

 <\/p>\n

Copy array using the spread operator<\/strong><\/p>\n

The Spread operator is also used to create a copy of an array. In the following example when an element is pushed to \u201carr2\u201d it also updates the original array \u201carr1\u201d.To avoid this Spread operator is used to create a copy array to avoid updating the original array.<\/p>\n

\"\"<\/p>\n

 <\/p>\n

Rest operator with function<\/strong><\/p>\n

The Spread operator allows the function to accept multiple arguments as an array. It is also used with destructuring to combine remaining elements into a single element.<\/p>\n

\"\"<\/p>\n

 <\/p>\n

Rest operator with destructuring<\/strong><\/p>\n

Rest operator can also be used with destructuring as the last element to combine the remaining element of the array into a single array. In the following example \u201clocation\u201d will contain all the remaining elements of the array.<\/p>\n
