JS minification ntim koj cov ntsiab lus rau hauv ntau qhov kev sib tw. JS yog qhov pib npaj rau koj cov kev pab cuam, tsis yog koj cov neeg siv khoom. Cov neeg tsim lub vev xaib tau txais txiaj ntsig zoo los ntawm qhov zoo tshaj plaws JavaScript minifying apparatuses los ua cov teeb meem tshwj xeeb ua haujlwm tau zoo. Qhov zoo tshaj plaws JS minifying cov cuab yeej pab cov neeg tsim qauv hauv lawv txoj haujlwm nce qib, thiab ntxiv rau kev txhim kho cov coding. Txhawm rau ua qhov coding ntau txwv, JavaScript minifying apparatus yog thov rau tshem tawm qhov chaw tsis xav tau, tsis muaj ntsiab lus, thaj chaw tsis muaj dab tsi, thiab cov lus hais tshiab los ntawm qhov chaws. Qhov zoo tshaj plaws JavaScript minifying instruments uas tus tsim qauv siv tau rau minifying JS yog:
1. JSMin.
2. YUI Compressor.
3. Packer.
