replace word in javascript

var str = "Please locate where 'locate' occurs!"; str.replace("locate", "W3Schools"); //replace only replace first match from string str.replace(/LOCATE/i, "W3Schools"); // i makes it case insensitive str.replace(/LOCATE/g, "W3Schools"); // g replace all matches from string rather than replacing only first document.write("<br>" + "replace:", res7); document.write("<br>" + "replace with case insensitive:", res8); document.write("<br>" + "replace all:", res9);

const p = 'The quick brown fox jumps over the lazy dog. If the dog reacted, was it really lazy?'; console.log(p.replaceAll('dog', 'monkey')); // expected output: "The quick brown fox jumps over the lazy monkey. If the monkey reacted, was it really lazy?"

function replaceAll(str, find, replace) { var escapedFind=find.replace(/([.*+?^=!:${}()|\[\]\/\\])/g, "\\$1"); return str.replace(new RegExp(escapedFind, 'g'), replace); } //usage example var sentence="How many shots did Bill take last night? That Bill is so crazy!"; var blameSusan=replaceAll(sentence,"Bill","Susan");

javascript string replace

const p = 'Its going to rain today and its going to rain tomorrow';

// Example of replacing all occurrances

// g = global search, which searches all instances
// i = case insensitive, which will match 'a' with 'A'

console.log(p.replace(regex, 'snow'));
// expected output: "Its going to snow today and its going to snow tomorrow"

// Example of replacing the first occurance
console.log(p.replace('rain', 'snow'));
