Searches a string for a string value, or a regular expression, and returns a new string where some or all matches are replaced.
searchValue is a string then only the first instance of the value will be replaced. To replace all instances, use the global (g) modifier on a regular expression.
const weather = `It's raining cats and dogs!`;const replaceCatsWithRats = weather.replace('cats', 'rats');console.log(replaceCatsWithRats);// Output: It's raining rats and dogs!
Find and replace multiple matches:
const kidsBook = 'Brown bear, brown bear, what do you see?';const birdsNotBears = kidsBook.replace(/bear/g, 'bird');console.log(birdsNotBears);// Output: Brown bird, brown bird, what do you see?
