How to use an array as literal In Javascript

Initializing an array using the array literal approach involves directly assigning square brackets [] to a variable. This creates an empty array or populates it with elements enclosed within the brackets, offering a concise and straightforward method for array initialization in JavaScript.

Example: Below is an example of array as literal.

Javascript
const sports = ["cricket", "football",
    "competitive-programming"];
console.log('sports=', sports);

const myArray = [];
console.log('myArray=', myArray);

const score = [420, 10, 1, 12, 102];
console.log('score=', score);

Output
sports= [ 'cricket', 'football', 'competitive-programming' ]
myArray= []
score= [ 420, 10, 1, 12, 102 ]

Example 2: The line breaks and new lines do not impact arrays, they store in their normal way.

Javascript
const sports = ["cricket",
    "football",
    "competitive-programming"];
console.log('sports=', sports);

const myArray = [];
console.log('myArray=', myArray);

const score = [420, 10, 1,
    12, 102];
console.log('score=', score);

Output
sports= [ 'cricket', 'football', 'competitive-programming' ]
myArray= []
score= [ 420, 10, 1, 12, 102 ]
