Create HTML file
Enter heading as “Remove spaces from a string using javascript “ in <h2></h2> tag
Enter string in bold tag <b></b> as “Original string is- “The earth has music for those who listen.”
Use button onclick removeSpaces()”
For passing content use <span> in paragraph tag <p></p> <p> New Sentence is: <span class=”outputString”></span> </p>
Initialize removespaces function const removeSpaces=()
Initialize string 1 and use replace () to only remove white spaces let str2 =
str1.replace(/ /g, “”);
For output use document.query selector () to return first element within the document that matches the specified selector document.querySelector(‘.outputString’).textContent
= str2;
