how to replace characters in a string javascript
var str = "Original string!";
var str = str.replace("Original", "New");const search = 'duck'
const replaceWith = 'goose';
const result = 'duck duck go'.replaceAll(search, replaceWith);
result; // => 'goose goose go'let a = "How to search and replace a char in a string";
while (a.search(" ", ""))
{
a = a.replace(" ", "");
}
console.log(a);str.replace(/hello/g, 'hi');
// the g is to show it's a global change, not one-time change.
str.replace(new RegExp('hello', 'g'), 'hi');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'
const regex = /rain/gi;
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'));
// expected output: "Its going to snow today and its going to rain tomorrow"
