How to convert an ASCII character into a hex value in TypeScript

Answer 1

function asciiToHex(ch: string) {
    // Get the ASCII value of the character
    const asciiValue: number = ch.charCodeAt(0);
    
    // Convert the ASCII value to a hexadecimal string
    const hexValue: string = asciiValue.toString(16);
    
    return hexValue;
}

const ch: string = 'A';

const hex_value: string = asciiToHex(ch);

console.log("The hexadecimal value of '" + ch + "' is 0x" + hex_value);

   
   
/*
run:
   
"The hexadecimal value of 'A' is 0x41" 
   
*/
