如何将一个句子中的英文词组或者英文+数字词组识别出来
新发布的三星盖乐世S9的特性如下：1.采用Exynos9810处理器；2.RAM为4GB；3.电池容量为3000mAh。

// Reset `lastIndex` if this regex is defined globally
// regex.lastIndex = 0;
let m;
while ((m = regex.exec(str)) !== null) {
// This is necessary to avoid infinite loops with zero-width matches
if (m.index === regex.lastIndex) {
regex.lastIndex++;
}
// The result can be accessed through the `m`-variable.
m.forEach((match, groupIndex) => {
console.log(`Found match, group ${groupIndex}: ${match}`);
});
