I tring to change single quotes to double quotes in text by Regular expression. (in single words) EXAMPLE: I'm go. You gona fly to planet 'Ziqtos' => I need to keep single quotes in I'm , and change to double in You gona fly "Ziqtos" Please help. There is my code.

    var myStr = "I, I can't deny I'm paralysed from the 'inside' Everyday I wake to feel the same And 'every' time you 'ask' me how I'm feeling I just smile and tell you 'that' I'm fine I, I don't know why I'm terrified of everything Just to call the doctor seems daunting For most of my life I felt a sharp uncertainty Now its just become a part of me I, I can't deny I'm paralysed from the inside Everyday I wake to feel the 'same' And every time you ask me how I'm feeling I just smile and tell you that I'm fine It's hard to stay true, to myself and to you I can't measure up to this girl you thought you knew This aching in my heart is tearing me apart But, darling all your love is somehow not 'enough' This aching in my heart is tearing me apart But, darling all your love is somehow not"

    var newStr = "";

    for (var i = 0; i < myStr.length; i++) {
        var lastIndex = myStr.search(/\s'[a-zA-Z]/ || /[a-zA-Z]'\s/);
        newStr += myStr.substr(0, lastIndex + 1);
        newStr += '\"';
        myStr = myStr.substr(lastIndex + 2);
    }

    var Phar = document.createElement("p");
    Phar.innerHTML = newStr;
    document.body.appendChild(Phar);

Code

See regex in use here

\B'|'\B

Alternatively, you can use \\B'(\\w+)'\\B and replace with "$1"

Usage

 const regex = /\\B'|'\\B/g; const str = `I'm go. You gona fly to planet 'Ziqtos'`; const str2 = `I, I can't deny I'm paralysed from the 'inside' Everyday I wake to feel the same And 'every' time you 'ask' me how I'm feeling I just smile and tell you 'that' I'm fine I, I don't know why I'm terrified of everything Just to call the doctor seems daunting For most of my life I felt a sharp uncertainty Now its just become a part of me I, I can't deny I'm paralysed from the inside Everyday I wake to feel the 'same' And every time you ask me how I'm feeling I just smile and tell you that I'm fine It's hard to stay true, to myself and to you I can't measure up to this girl you thought you knew This aching in my heart is tearing me apart But, darling all your love is somehow not 'enough' This aching in my heart is tearing me apart But, darling all your love is somehow not`; const subst = `"`; // The substituted value will be contained in the result variable const result = str.replace(regex, subst); const result2 = str2.replace(regex, subst); console.log(result); console.log(result2);

Answer 2

in your scenario you can get away with this regex /\\'(\\w+)\\'/g :

 var myStr = "I, I can't deny I'm paralysed from the 'inside' Everyday I wake to feel the same And 'every' time you 'ask' me how I'm feeling I just smile and tell you 'that' I'm fine I, I don't know why I'm terrified of everything Just to call the doctor seems daunting For most of my life I felt a sharp uncertainty Now its just become a part of me I, I can't deny I'm paralysed from the inside Everyday I wake to feel the 'same' And every time you ask me how I'm feeling I just smile and tell you that I'm fine It's hard to stay true, to myself and to you I can't measure up to this girl you thought you knew This aching in my heart is tearing me apart But, darling all your love is somehow not 'enough' This aching in my heart is tearing me apart But, darling all your love is somehow not" var txt = myStr.replace(/\\'(\\w+)\\'/g, (_,m) => '"' + m + '"' ) document.querySelector('div').textContent= txt 

 <div> 

this will work as long as you want to change the quotes to single words.
