Convert Number, String, Float and Format JSON

 1) Convert to String

To quickly convert a number to a string, we can use the concatenation operator (+) plus followed by an empty set of quotation marks "" .

let val = 1 + "";
console.log(val); // Result: "1"
console.log(typeof val); // Result: "string"

2) Convert to Number

The opposite can be quickly achieved using the addition operator + .

let int = "15";
int = +int;
console.log(int); // Result: 15
console.log(typeof int); Result: "number"

This may also be used to convert Booleans to numbers, as below:

console.log(+true);  // Return: 1
console.log(+false); // Return: 0

3)Quick Float to Integer

If you want to convert a float to an integer, you can use Math.floor() , Math.ceil() or Math.round() . But there is also a faster way to truncate a float to an integer using |, the bitwise OR operator.

console.log(23.9 | 0);  // Result: 23
console.log(-23.9 | 0); // Result: -23

4)Format JSON Code

Lastly, you may have used JSON.stringify before, but did you realise it can also help indent your JSON for you?
The stringify() method takes two optional parameters: a replacer function, which you can use to filter the JSON that is displayed, and a space value.
The space value takes an integer for the number of spaces you want or a string (such as '\t' to insert tabs), and it can make it a lot easier to read fetched JSON data.

console.log(JSON.stringify({ alpha: 'A', beta: 'B' }, null, '\t'));
// Result:
// '{
//     "alpha": A,
//     "beta": B
// }'

Get Query Params

window.location object has a bunch of utility methods and properties. We can get information about the protocol, host, port, domain, etc from the browser URLs using these properties and methods. 

var args = window.location.search
let data = new URLSearchParams(location.search).get('reqId');
console.log(data)

Few Javascript or JQuery Tricks for array and operators

 1) Empty an array

var arr = [10 , 20 , 30 ];
arr.length = 0; // arr will be equal to [].

2) Truncate an array using length

Like the previous example of emptying an array, we truncate it using the length property.

var arr = [10, 20, 30, 40, 50, 60, 70, 80, 90];
arr.length = 4; // arr will be equal to [10, 20, 30, 40].

As a bonus, if you set the array length to a higher value, the length will be changed and new items will be added with undefined as a value. The array length is not a read only property.

arr.length = 10; // the new array length is 10
arr[arr.length - 1] ; // arr [10, 20, 30, 40, 50, 60, 70, 80, 90, undefined];

3)Use logical AND/ OR for conditions

var foo = 10;
foo == 10 && doSomething(); // is the same thing as if (foo == 10) doSomething();
foo == 5 || doSomething(); // is the same thing as if (foo != 5) doSomething();

4) Comma operator

var a = 10;
var b = ( a++, 99 );
console.log(a);  // a will be equal to 10
console.log(b);  // b is equal to 99

5) Swap variables

let v1 = 'value 1';
let v2 = 'value 2';

[v1,v2] = [v2, v1];
console.log(v1, v2);

Calculate date difference using JQuery

Simple way to get days between 2 dates...

var date1 = new Date("12/13/2021"); // MM/dd/yyyy var date2 = new Date("01/01/2021"); // MM/dd/yyyy // date1 - date2 returns difference in milliseconds var diff = new Date(date1 - date2); // get days var days = diff/1000/60/60/24; console.log(days)

Add days to a Date using JavaScript

Many times I have face this issue, and hope you too.. this is simple 3 line of code will help and fix this problem.

let days =7 ; // we are going to add 7 days to a date

let cdt = new Date('2021-01-10'); // your date value

let tdt = cdt.setTime(cdt.getTime() + (days * 24 * 60 * 60 * 1000)); // calculation for adding 7 days and adding to time

let targetDT = new Date(tdt).format("yyyy-MM-dd"); // converting back from time to date 

// Output for targetDT will be "2021-01-17"

// With function...

function addDays(theDate, days) {

    return new Date(theDate.getTime() + days*24*60*60*1000);

}

var newDate = addDays(new Date(), 5);

Hope this will help you...

JavaScript to get index from a JSON object with value

 In modern browsers you can use findIndex:

var students = [ {id: 100 }, {id: 200}, {id: 300}, {id: 400}, {id: 500} ]; var index = students.findIndex(std=> std.id === 200);

But this function is not supported by even not so old versions of a few browser as well as in IE (EDGE supports it). So below is a workaround using javascript: You can use either Array.forEach or Array.find or Array.filter

var students = [ {id: 100 }, {id: 200}, {id: 300}, {id: 400}, {id: 500} ]; var index = -1; var needle = 200; var filteredRes = students.find(function(item, i){ if(item.id === needle){ index = i; return i; } }); console.log(index, filteredRes); /*Result: 1 Object { id: 200 }*/

This method takes little more overhead as it loops through the whole object to search for the match. So, for lengthy JSON data, this method is not suggested(even though it gets the work done).
