const arr = ["The", "coding"];
arr.push("Master");
//["The", "Coding", "Master"]

const arr = ["The", "Coding", "Master"];
arr.tostring();

const arr = ["The", "Coding", "Master"];
arr.shift();
//["Coding", "Master"]

const arr = ["The", "Coding", "Master"];
arr.pop();
///["The", "Coding"]
- FILTER
The filter() method creates an array filled with all array elements that pass a test (provided as a function).
const arr = ["The", "Coding", "Master"];
arr.filter(word =>word.length > 3);
//["Coding", "Master"]
- INCLUDES

const arr = ["The", "Coding", "Master"];
