ES6: 16 Use Destructuring Assignment to Pass an Object as a Function's Parameters


in some cases, you can destructure the object in a function argument itself. Consider the code below:
const profileUpdate = (profileData) => {
const { name, age, nationality, location } = profileData;
// do something with these variables
}
This effectively destructures the object sent into the function. This can also be done in-place:
const profileUpdate = ({ name, age, nationality, location }) => {
/* do something with these fields */
}
This removes some extra lines and makes our code look neat. This has the added benefit of not having to manipulate an entire object in a function; only the fields that are needed are copied inside the function. Use destructuring assignment within the argument to the function half to send only max and min inside the function.
const stats = {
max: 56.78,
standard_deviation: 4.34,
median: 34.54,
mode: 23.87,
min: -0.75,
average: 35.85
};
const half = (function() {
"use strict"; // do not change this line
return function half({max,min}) { //instead op passing whole stats object just pass max,min in braces {}
// use function argument destructuring
return (max + min) / 2.0;
};
})();
console.log(stats); // should be object
console.log(half(stats)); // should be 28.015

ES6 : 5 Prevent Object Mutation

As seen in the previous post declaration alone doesn't really protect your data from mutation. To ensure your data doesn't change, JavaScript provides a function Object.freeze() to prevent data mutation. Once the object is frozen, you can no longer add, update, or delete properties from it. Any attempt at changing the object will be rejected without an error. let obj = { name:"FreeCodeCamp" review:"Awesome" }; Object.freeze(obj); obj.review = "bad"; //will be ignored. Mutation not allowed obj.newProp = "Test"; // will be ignored. Mutation not allowed console.log(obj); // { name: "FreeCodeCamp", review:"Awesome"}

ES6: 1 Explore Differences Between the var and let Keywords

One of the biggest problems with declaring variables with the var keyword is that you can overwrite variable declarations without an error. var camper = 'James'; var camper = 'David'; console.log(camper); // logs 'David' As you can see in the code above, the camper variable is originally declared as James and then overridden to be David . In a small application, you might not run into this type of problem, but when your code becomes larger, you might accidentally overwrite a variable that you did not intend to overwrite. Because this behavior does not throw an error, searching and fixing bugs becomes more difficult. A new keyword called let was introduced in ES6 to solve this potential issue with the var keyword. If you were to replace var with let in the variable declarations of the code above, the result would be an error. let camper = 'James'; let camper = 'David'; // throws an error This error can be seen...

CSS Grid: Reduce Repetition Using the repeat Function

 When we used grid-template-columns and grid-template-rows to define the structure of a grid, you entered a value for each row or column you created. Lets say you want a grid with 100 rows of the same height. It isn't very practical to insert 100 values individually. Fortunately, there's a better way - by using the repeat function to specify the number of times you want your column or row to be repeated, followed by a comma and the value you want to repeat. Here's an example that would create the 100 row grid, each row at 50px tall. grid-template-rows: repeat(100, 50px); You can also repeat multiple values with the repeat function, and insert the function amongst other values when defining a grid structure. Here's what I mean: grid-template-columns: repeat(2, 1fr 50px) 20px;  this will be translated to :            grid-template-columns:1fr 50px 1fr 50px  20px;   1fr 50px is repeated t...
