Encode vs Encode Component — what’s the difference?

encodeURI("https://example.com/path?q=hello world&lang=en")
// → "https://example.com/path?q=hello%20world&lang=en"
// Keeps :, /, ?, &, = intact

// → "hello%20world%26lang%3Den"
// Encodes EVERYTHING except letters, digits, - _ . ~

Use encodeURI for full URLs. Use encodeURIComponent for individual query parameter values.
