Converting ASCII to hexadecimal in JavaScript
We are required to write a JavaScript function that takes in a string that represents a ASCII number. The function should convert the number into its corresponding hexadecimal code and return the hexadecimal.
For example −
f the input ASCII string is −
const str = '159';
Then the hexadecimal code for this should be 313539.
Example
Following is the code −
const str = '159';
const convertToHexa = (str = '') =>{
const res = [];
const { length: len } = str;
for (let n = 0, l = len; n < l; n ++) {
const hex = Number(str.charCodeAt(n)).toString(16);
res.push(hex);
};
return res.join('');
}
console.log(convertToHexa('159'));Output
Following is the output on console −
313539
