remove whitespace due to line breaks javascript code example

Example 1: javascript remove line breaks from string

var stringWithLineBreaks = `
O boy 
I've got 
Breaks
`;
var stringWithoutLineBreaks = stringWithLineBreaks.replace(/(\r\n|\n|\r)/gm, "");//remove those line breaks

Example 2: split whitespace except in quotes javascript

// Hard to read, but works
// If you want to keep the \ in the string, replace the: c.replace(/\\(.)/,"$1"); by: c;

keywords.match(/\\?.|^$/g).reduce((p, c) => {
        if(c === '"'){
            p.quote ^= 1;
        }else if(!p.quote && c === ' '){
            p.a.push('');
        }else{
            p.a[p.a.length-1] += c.replace(/\\(.)/,"$1");
        }
        return  p;
    }, {a: ['']}).a
