Generally speaking, if you're doing front-end Web development, you are likely to work with JavaScript, HTML, and CSS (and related libraries/frameworks, e.g. React, Bootstrap...). You could also use JavaScript in some other context - for example JavaScript is used on the server-side too, such as with the Express framework. You can also develop for mobile using JavaScript, for example with React Native.
