The Swedish J is commonly pronounced like [j]. This means that it’s rather pronounced like a Y (e.g. yum) than an English J [ʤ] (dj) (e.g. jar).
Also English loan words are pronounced the Swedish way. Jeans is rather pronounced like yeens. French loan words get a ske-sound [ɧ] instead.
English loans → [j]
French loans → [ɧ]
