Converting whitespace string to url in JavaScript
In web urls if we provide space in the url, the browser automatically replaces all the spaces with the string '%20'
We are required to write a JavaScript function that takes in a string as the first and the only argument. The function should then construct and return a new string in which a whitespace, wherever it was in place, replaced by '%20'
For example −
If the input string is −
const str = 'some extra Space';
Then the output should be −
const output = 'some%20extra%20%20Space';
Example
The code for this will be −
const str = 'some extra Space';
const replaceWhitespace = (str = '') => {
let res = '';
const { length } = str;
for(let i = 0; i < length; i++){
const char = str[i];
if(!(char === ' ')){
res += char;
}else{
res += '%20';
};
};
return res;
};
console.log(replaceWhitespace(str));Output
And the output in the console will be −
some%20extra%20%20Space
