JavaScript, Functions in Object in ES6, Clear Your Doubt

JavaScript Object Method Syntax
In JS, the function keyword is not used inside object when any function is defined. e.g.
const serpant = {
length: 100,
weight: 30,
craw() {
console.log("I can crawl on any surface with speed: 50");
},
drink() {
console.log("can drink milk");
},
};
Why?
Answer: In JavaScript, when defining functions as methods within an object, the function keyword can be omitted for a more concise syntax. This is part of the object literal syntax enhancements introduced in ECMAScript 2015 (ES6).
Here’s a breakdown of the syntax:Prior to ES6, defining a method within an object required the function keyword:

const serpant = {
length: 100,
weight: 30,
craw: function() {
console.log("I can crawl on any surface with speed: 50");
},
drink: function() {
console.log("can drink milk");
}
};
With ES6, methods can be defined more concisely by omitting the function keyword:

const serpant = {
length: 100,
weight: 30,
craw() {
console.log("I can crawl on any surface with speed: 50");
},
drink() {
console.log("can drink milk");
}
};
1. Conciseness: The ES6 method shorthand makes the code more concise and readable by reducing redundancy. There is no need to repeatedly type 'function' when defining methods within an object.
2. Consistency: It aligns with other ES6 syntax improvements aimed at making JavaScript more consistent and easier to write.
3. Improved Syntax: The shorthand syntax is cleaner and more modern, fitting well with other ES6 features like arrow functions, template literals, and destructuring.The two syntaxes are functionally equivalent. The method shorthand is purely syntactic sugar, providing no functional difference or performance improvement over the traditional method definition.
In summary, the omission of the function keyword inside object literals when defining methods is part of the ES6 enhancements to make JavaScript more concise and easier to read.
