For this, use toUpperCase() along with toLowerCase(). Following is the code −Examplefunction capitalEveryFirstletter(subjectTitle) {    return subjectTitle.split(' ')    .map(st => st.charAt(0).toUpperCase() + st.slice(1).toLowerCase())    .join(' ');; } var subjectTitle="iNtroduction tO JavaScript ProgRAMMINg"; var output=capitalEveryFirstletter(subjectTitle); console.log("The result="+output);To run the above program, you need to use the following command −node fileName.js.Here, my file name is demo74.js.OutputThis will produce the following output −PS C:\Users\Amit\JavaScript-code> node demo74.js The result=Introduction To JavaScript Programming

To create a global variable, you need to place variable inside the tag. Following is the code −Example Live Demo Document checkGlobalVariable    var globalVariable;    $(document).ready(function() {       function initializeGlobalVariable() {          globalVariable = [{             "name":"John",             "age":23          }];       }       initializeGlobalVariable();    });    function createGlobalVariable() {       if (globalVariable.length) {          console.log('The Global variable name   ...

For this, you need to use “flex-direction” concept of CSS. Let’s say the following is our CSS style −    .demo{       display: flex;       flex-direction: column-reverse;    } Now, set the div position relative to another div −Example Live Demo Document    .demo{       display: flex;       flex-direction: column-reverse;    } DIV_DEMO1 DIV_DEMO2 To run the above program, save the file name “anyName.html(index.html)” and right click on the file. Select the option “Open with Live Server” in VS Code editor.OutputThis will produce the following output −

You can use keyword async as well as await. Following is the code −Exampleasync function test(i) {    while (i node demo73.js Call Demo1() Call Demo2() Call Demo1() Call Demo2() Call Demo1() Call Demo2() Call Demo1() Call Demo2() Call Demo1() Call Demo2() Call Demo1() Call Demo2() Call Demo1() Call Demo2() Call Demo1() Call Demo2() Call Demo1() Call Demo2() Call Demo1() Call Demo2()

To get value of any attribute from XML data, use attr() in JavaScript. Following is the code −Example Live Demo Document    var yourXMLDetails = ''    +''    +''    +''    console.log("Game Details==="+$(yourXMLDetails).attr("details")); To run the above program, save the file name “anyName.html(index.html)” and right click on the file. Select the option “Open with Live Server” in VS Code editor.OutputThis will produce the following output −

Let’s say the following is our object −var customerDetails= [    {       customerId:101,       customerName:"John"    },    {       customerId:102,       customerName:"David"    },    {       customerId:103,       customerName:"Mike"    },    {       customerId:104,       customerName:"Bob"    } ]Use for loop with the following condition to display only odd CustomerID records −for(var index=0;index

You can use the concept of createHTMLDocument(). Following is the code −Example Document    const htmlDocument = document.implementation.createHTMLDocument();    const customURL = htmlDocument.createElement( 'base' );    customURL.href = "https://www.tutorialspoint.com/java/index.htm";    htmlDocument.head.append( customURL );    console.log("Base URL="+customURL.href);    const modifiedURL = htmlDocument.createElement("a");    modifiedURL.href = "../java/java_questions_answers.html";    htmlDocument.body.append( modifiedURL );    console.log("After Modifying URL="+ modifiedURL.href ); To run the above program, save the file name “anyName.html(index.html)” and right click on the file. Select the option “Open with Live Server” in VS Code editor.OutputThis will produce the following output: on ... Read More

To select all elements with “data-“ attribute, use document.querySelectorAll(“”). Following is the code −Example Live Demo Document    var result=document.querySelectorAll('[data-sentence]');    for (var index in result){       if (result.hasOwnProperty(index)){          console.log(result[index].getAttribute('data-sentence'));       }    } To run the above program, save the file name “anyName.html(index.html)” and right click on the file. Select the option “Open with Live Server” in VS Code editor.OutputThis will produce the following output −

To match multiple occurrences in a string, use regular expressions. Following is the code −Examplefunction checkMultipleOccurrences(sentence) {    var matchExpression = /(JavaScript?[^\s]+)|(typescript?[^\s]+)/g;    return sentence.match(matchExpression); } var sentence="This is my first JavaScript Program which is the subset of typescript"; console.log(sentence); console.log(checkMultipleOccurrences(sentence));To run the above program, you need to use the following command −node fileName.js.Here, my file name is demo70.js.OutputThis will produce the following output −PS C:\Users\Amit\JavaScript-code> node demo70.js This is my first JavaScript Program which is the subset of typescript [ 'JavaScript', 'typescript' ]

A matrix can be converted into a pixel’s image of matrix. It is defined as the area of the matrix which contains pixels with equal or different sizes of left, right, bottom and upper.We can create this by using image function and its argument useRaster with the matrix data.Example Live Demo> M par(mar=c(5,5,5,5)) > image(M,useRaster=TRUE,axes=FALSE)Output> par(mar=c(10,10,10,10)) > image(M,useRaster=TRUE,axes=FALSE)Output> par(mar=c(2,2,2,2)) > image(M,useRaster=TRUE,axes=FALSE)OutputPixel matrix with grey color −> image(M,axes=FALSE,col=grey(seq(0,1,length=180)))Output
