float_num.toFixed(2);
Here is what the above code is Doing:
1. We’re creating a variable called float_num and assigning it the value of 1.2345.
2. We’re creating a variable called rounded_float_num and assigning it the value of float_num rounded to 2 decimal places.
3. We’re creating a variable called fixed_float_num and assigning it the value of float_num rounded to 2 decimal places.
$inner = [“b” => “i”, “c” => “i”]; $outer = [“a” => “o”, “c” => “o”]; var_dump(array_merge($outer, $inner)); var_dump(array_merge($inner, $outer)); Here is what the above code is Doing: 1. It creates an array $inner with keys “b” and “c” and values “i” and “i”. 2. It creates an array $outer with keys “a” and “c”…
var tz = moment.tz.guess(); Here is what the above code is Doing: 1. We’re importing the moment.js library. 2. We’re importing the moment-timezone library. 3. We’re creating a variable called tz and setting it equal to the timezone that the user is in.
var min = parseInt(“2”); var max = parseInt(“3″); Here is what the above code is Doing: 1. We’re creating a variable called “min” and setting it equal to the integer 2. 2. We’re creating a variable called “max” and setting it equal to the integer 3. 3. We’re creating a variable called “randomNumber” and setting…
function leftPad(number, targetLength) { var output = number + ”; while (output.length < targetLength) { output = '0' + output; } return output; } // Output :- // leftPad(1, 2) // 01 // leftPad(10, 2) // 10 // leftPad(100, 2) // 100 // leftPad(1, 3) // 001 // leftPad(1, 8) // 00000001 Here is what...
// create an array with length 7 […Array(7).keys()] Here is what the above code is Doing: 1. Array(7) creates an array with 7 empty slots. 2. .keys() creates an iterator that contains the keys of the array. 3. The spread operator (…) turns the iterator into an array.
const myInput = document.querySelector(‘input[name=”exampleInput”]’); myInput.addEventListener(“change”, (e) => { // here we do something }); Here is what the above code is Doing: 1. We select the input element with the name attribute of exampleInput. 2. We add an event listener to the input element. 3. We listen for the change event. 4. We do something…
