You can implement a function to be called before the user leaves a page with Javascript as follows: 1 2 3 window.onbeforeunload = function(e) { return "Do you want to exit this page?"; }; This is a typically solution for when you want the user to confirm their changes are saved before allowing them to close the current page in editing tools.

If you need to calculate the multiples of 3, starting from 1 up until 1000, then you can use the following code: 1 2 3 4 5 n = 1 v = [] while n <= 1000: v.append(n) n = n + 3 This will generate the list of numbers which are the multiples of 3 from 1 to 1000: 1 1, 4, 7, 10, 13, 16, 19, 22, 25, 28, 31, 34, 37, 40, 43, 46, 49, 52, 55, 58, 61, 64, 67, 70, 73, 76, 79, 82, 85, 88, 91, 94, 97, 100, 103, 106, 109, 112, 115, 118, 121, 124, 127, 130, 133, 136, 139, 142, 145, 148, 151, 154, 157, 160, 163, 166, 169, 172, 175, 178, 181, 184, 187, 190, 193, 196, 199, 202, 205, 208, 211, 214, 217, 220, 223, 226, 229, 232, 235, 238, 241, 244, 247, 250, 253, 256, 259, 262, 265, 268, 271, 274, 277, 280, 283, 286, 289, 292, 295, 298, 301, 304, 307, 310, 313, 316, 319, 322, 325, 328, 331, 334, 337, 340, 343, 346, 349, 352, 355, 358, 361, 364, 367, 370, 373, 376, 379, 382, 385, 388, 391, 394, 397, 400, 403, 406, 409, 412, 415, 418, 421, 424, 427, 430, 433, 436, 439, 442, 445, 448, 451, 454, 457, 460, 463, 466, 469, 472, 475, 478, 481, 484, 487, 490, 493, 496, 499, 502, 505, 508, 511, 514, 517, 520, 523, 526, 529, 532, 535, 538, 541, 544, 547, 550, 553, 556, 559, 562, 565, 568, 571, 574, 577, 580, 583, 586, 589, 592, 595, 598, 601, 604, 607, 610, 613, 616, 619, 622, 625, 628, 631, 634, 637, 640, 643, 646, 649, 652, 655, 658, 661, 664, 667, 670, 673, 676, 679, 682, 685, 688, 691, 694, 697, 700, 703, 706, 709, 712, 715, 718, 721, 724, 727, 730, 733, 736, 739, 742, 745, 748, 751, 754, 757, 760, 763, 766, 769, 772, 775, 778, 781, 784, 787, 790, 793, 796, 799, 802, 805, 808, 811, 814, 817, 820, 823, 826, 829, 832, 835, 838, 841, 844, 847, 850, 853, 856, 859, 862, 865, 868, 871, 874, 877, 880, 883, 886, 889, 892, 895, 898, 901, 904, 907, 910, 913, 916, 919, 922, 925, 928, 931, 934, 937, 940, 943, 946, 949, 952, 955, 958, 961, 964, 967, 970, 973, 976, 979, 982, 985, 988, 991, 994, 997, 1000

If you need to count how many files are in a directory on Linux, then you can use a combination of the ls command to list all the files, and the wc command to count how many lines are printed: Option 1 – Using wc 1 ls | wc -l You can specify a directory as follows: 1 ls <directory> | wc -l Option 2 – Using find You can count files recursively by using the find command:

If you need to read a file line by line in Java, then you can use one of the following three (3) options. Option 1 You can use the FileReader and BufferedReader packages as follows: 1 2 3 4 5 6 7 8 9 10 11 File file = new File("./your/file.txt"); try (FileReader fr = new FileReader(file); BufferedReader br = new BufferedReader(fr);) { String line; while ((line = br.readLine()) != null) { System.

You can use Java’s StringBuilder to create and manipulate Strings as follows: 1 2 3 4 5 StringBuilder sb = new StringBuilder(); sb.append("Some").append(" ").append("String"); System.out.println(sb.toString()); // "Some String" The following three (3) options allow you to clear or empty a StringBuilder. Option 1 – using setLength 1 sb.setLength(0); Option 2 – reinstantiating 1 sb = new StringBuilder(); Option 3 – using delete 1 sb.delete(0, sb.length());

Sometimes you will need to manually approve a SageMaker model package from the AWS CLI. Step 1 – Get a list of the available packages 1 aws sagemaker list-model-packages --model-package-group-name "the-model-package-group" This will produce the following output: 1 2 3 4 5 6 7 8 9 10 11 12 13 14 { "ModelPackageSummaryList": [ { "ModelPackageGroupName": "...", "ModelPackageVersion": "...", "ModelPackageArn": "the-arn-we-will-use-below", "ModelPackageDescription": "...", "CreationTime": "...", "ModelPackageStatus": "Completed", "ModelApprovalStatus": "PendingManualApproval" }, .

If you need to assume role between AWS accounts, or allow an account to assume a role and use resources in another AWS account, then you need to create a role and attach the following policy. The following two (2) steps creates a Trust Relationship between the accounts. Step 1 – In the Source Account 1 2 3 4 5 6 7 8 9 10 11 12 { "Version": "2012-10-17", "Statement": [{ "Effect": "Allow", "Action": [ "sts:AssumeRole" ], "Resource": [ "arn:aws:iam::DESTINATION-ACCOUNT-ID:role/DESTINATION-ROLENAME" ] }] } Step 2 – In the Destination Account 1 2 3 4 5 6 7 8 9 10 { "Version": "2012-10-17", "Statement": [{ "Effect": "Allow", "Principal": { "AWS": "arn:aws:iam::SOURCE-ACCOUNT-ID:role/SOURCE-USERNAME" }, "Action": "sts:AssumeRole" }] }

If you need to style an element using Javascript then you can use the style object to support all your CSS needs. 1 2 3 4 5 6 7 8 9 10 11 12 13 <html> <body> <p id="p1">Hello World!</p> <script> document.getElementById("p1").style.color = "red"; </script> <p>The paragraph above was changed by a script.</p> </body> </html> If you need to do this purely in a Javascript file itself, then: 1 2 3 4 5 6 // Get a reference to the element var myElement = document.

If you need your Javascript code to wait one (1) second (or more) while executing, then there are a couple of ways to achieve this. Option 1 – Creating a delay Promise 1 2 3 4 5 function delay(time) { return new Promise(resolve => setTimeout(resolve, time)); } delay(1000).then(() => console.log('ran after 1 second elapsed')); Option 2 – Using setTimeout 1 2 3 setTimeout(function(){ console.log("Ready") }, 1000); Option 3 – Using an async Promise 1 2 3 4 5 6 7 async function test() { console.

Arrays come with a useful forEach function that allows you to loop through the array. 1 2 3 4 5 6 7 8 9 var colors = ['red', 'blue', 'green']; colors.forEach(function(color) { console.log(color); }); // red // blue // green You can also get the index in each loop as follows: 1 2 3 4 5 6 7 8 9 const colors = ['red', 'blue', 'green']; colors.forEach((item, index)=>{ console.log(index, item) }); // 0 'red' // 1 'blue' // 2 'green'

If you need to remove an element from an array in Javascript, then you can use one of the following five (5) options: Option 1 – Use splice to remove an element Example 1 using splice: 1 2 3 4 5 var colors = ["red","blue","car","green"]; var carIndex = colors.indexOf("car"); colors.splice(carIndex, 1); // colors = ["red","blue","green"] Example 2 using splice: 1 2 3 4 var myArray = ["Sunday", "Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday"]; // Remove Sunday -- index 0 and Monday -- index 1 myArray.

If you need to get an array of alphabetical letters in Javascript then you can use one of the following: Option 1 – Explicitly define the array first 1 const alphabet = ["a","b","c","d","e","f","g","h","i","j","k","l","m","n","o","p","q","r","s","t","u","v","w","x","y","z"]; Option 2 – Split a string of alphabetical characters 1 const alphabetArray = "abcdefghijklmnopqrstuvwxyz".split(""); Option 3 – Split a string and UpperCase characters 1 const alphabetArrayUp = toUpperCase("abcdefghijklmnopqrstuvwxyz").split("");

With the Power of Two, you can ask the following: How do you find the powers of 2? What does the power of 2 stand for? How much is the power of 2?

Javascript gives a few options to determine the screen width. When we say screen, we mean the browser window’s width itself. Option 1 – Using Native Javascript Using native Javascript objects, we can find the innerWidth and innerHeight: 1 2 var w = window.innerWidth; var h = window.innerHeight; The window object also allows for: 1 2 3 window.screen.width // or simply screen.width We can write some code to tell us the width and height with fallbacks:

If you need to read a file in Rust, then you can use the fs package from the standard library: 1 2 3 4 5 6 7 8 use std::fs; fn main() { let contents = fs::read_to_string(filename) .expect("Something went wrong reading the file"); println!("With text:\n{}", contents); }
